Functional Description
The IC41C16100A(S) and IC41LV16100A(S) is a CMOSDRAM optimized for high-speed bandwidth, low powerapplications. During READ or WRITE cycles, each bit isuniquely addressed through the 16 address bits. Theseare entered ten bits (A0-A9) at a time. The row address islatched by the Row Address Strobe (RAS). The columnaddress is latched by the Column Address Strobe (CAS).RAS is used to latch the first ten bits and CAS is used thelatter ten bits.
The IC41C16100A(S) and IC41LV16100A(S) has two CAScontrols, LCAS and UCAS. The LCAS and UCAS inputsinternally generates a CAS signal functioning in an iden-tical manner to the single CAS input on the other 1M x 16DRAMs. The key difference is that each CAS controls itscorresponding I/O tristate logic (in conjunction with OEand WE and RAS). LCAS controls I/O0 through I/O7 andUCAS controls I/O8 through I/O15.
The IC41C16100A(S) and IC41LV16100A(S) CAS func-tion is determined by the first CAS (LCAS or UCAS)transitioning LOW and the last transitioning back HIGH.The two CAS controls give the IC41C16100A(S) andIS41LV16100A(S) both BYTE READ and BYTE WRITEcycle capabilities.
cycle, an internal 10-bit counter provides the row ad-dresses and the external address inputs are ignored.CAS-before-RAS is a refresh-only mode and no dataaccess or device selection is allowed. Thus, the outputremains in the High-Z state during the cycle.
Self Refresh Cycle
The Self Refresh allows the user a dynamic refresh, dataretention mode at the extended refresh period of 128 ms.i.e., 125 µs per row when using distributed CBR refreshes.The feature also allows the user the choice of a fully static,low power data retention mode. The optional Self Refreshfeature is initiated by performing a CBR Refresh cycle andholding RAS LOW for the specified tRASS.
The Self Refresh mode is terminated by driving RAS HIGHfor a minimum time of tRPS. This delay allows for thecompletion of any internal refresh cycles that may be inprocess at the time of the RAS LOW-to-HIGH transition.If the DRAM controller uses a distributed refresh sequence,a burst refresh is not required upon exiting Self Refresh.However, if the DRAM controller utilizes a RAS-only orburst refresh sequence, all 1,024 rows must be refreshedwithin the average internal refresh rate, prior to the re-sumption of normal operation.
Memory Cycle
A memory cycle is initiated by bring RAS LOW and it isterminated by returning both RAS and CAS HIGH. Toensures proper device operation and data integrity anymemory cycle, once initiated, must not be ended oraborted before the minimum tRAS time has expired. A newcycle must not be initiated until the minimum prechargetime tRP, tCP has elapsed.
Extended Data Out Page Mode
EDO page mode operation permits all 1,024 columnswithin a selected row to be randomly accessed at a highdata rate.
In EDO page mode read cycle, the data-out is held to thenext CAS cycle’s falling edge, instead of the rising edge.For this reason, the valid data output time in EDO pagemode is extended compared with the fast page mode. Inthe fast page mode, the valid data output time becomesshorter as the CAS cycle time becomes shorter. Therefore,in EDO page mode, the timing margin in read cycle islarger than that of the fast page mode even if the CAScycle time becomes shorter.
In EDO page mode, due to the extended data function, theCAS cycle time can be shorter than in the fast page modeif the timing margin is the same.
The EDO page mode allows both read and write opera-tions during one RAS cycle, but the performance isequivalent to that of the fast page mode in that case.
Read Cycle
A read cycle is initiated by the falling edge of CAS or OE,whichever occurs last, while holding WE HIGH. Thecolumn address must be held for a minimum time specifiedby tAR. Data Out becomes valid only when tRAC, tAA, tCACand tOEA are all satisfied. As a result, the access time isdependent on the timing relationships between theseparameters.
Write Cycle
A write cycle is initiated by the falling edge of CAS andWE, whichever occurs last. The input data must be validat or before the falling edge of CAS or WE, whicheveroccurs first.
Power-On
After application of the VCC supply, an initial pause of200 µs is required followed by a minimum of eight initial-ization cycles (any combination of cycles containing aRAS signal).
During power-on, it is recommended that RAS track withVCC or be held at a valid VIH to avoid current surges.
Refresh Cycle
To retain data, 1,024 refresh cycles are required in each16 ms period. There are two ways to refresh the memory.1.By clocking each of the 1,024 row addresses (A0through A9) with RAS at least once every 16 ms. Anyread, write, read-modify-write or RAS-only cycle re-freshes the addressed row.
2.Using a CAS-before-RAS refresh cycle. CAS-before-RAS refresh is activated by the falling edge of RAS,while holding CAS LOW. In CAS-before-RAS refreshIntegrated Circuit Solution Inc.

Notes:
1.An initial pause of 200 µs is required after power-up followed by eight RAS refresh cycle (RAS-Only or CBR) before proper device
operation is assured. The eight RAS cycles wake-up should be repeated any time the tREF refresh requirement is exceeded.2.VIH (MIN) and VIL (MAX) are reference levels for measuring timing of input signals. Transition times, are measured between VIH
and VIL (or between VIL and VIH) and assume to be 1 ns for all inputs.
3.In addition to meeting the transition rate specification, all input signals must transit between VIH and VIL (or between VIL and VIH)
in a monotonic manner.
4.If CAS and RAS = VIH, data output is High-Z.
5.If CAS = VIL, data output may contain data from the last valid READ cycle.6.Measured with a load equivalent to one TTL gate and 50 pF.
7.Assumes that tRCD < tRCD (MAX). If tRCD is greater than the maximum recommended value shown in this table, tRAC will increase
by the amount that tRCD exceeds the value shown.8.Assumes that tRCD > tRCD (MAX).
9.If CAS is LOW at the falling edge of RAS, data out will be maintained from the previous cycle. To initiate a new cycle and clear the
data output buffer, CAS and RAS must be pulsed for tCP.
10.Operation with the tRCD (MAX) limit ensures that tRAC (MAX) can be met. tRCD (MAX) is specified as a reference point only; if tRCD
is greater than the specified tRCD (MAX) limit, access time is controlled exclusively by tCAC.
11.Operation within the tRAD (MAX) limit ensures that tRCD (MAX) can be met. tRAD (MAX) is specified as a reference point only; if tRAD
is greater than the specified tRAD (MAX) limit, access time is controlled exclusively by tAA.12.Either tRCH or tRRH must be satisfied for a READ cycle.
13.tOFF (MAX) defines the time at which the output achieves the open circuit condition; it is not a reference to VOH or VOL.
14.tWCS, tRWD, tAWD and tCWD are restrictive operating parameters in LATE WRITE and READ-MODIFY-WRITE cycle only. If tWCS > tWCS
(MIN), the cycle is an EARLY WRITE cycle and the data output will remain open circuit throughout the entire cycle. If tRWD > tRWD(MIN), tAWD > tAWD (MIN) and tCWD > tCWD (MIN), the cycle is a READ-WRITE cycle and the data output will contain data read fromthe selected cell. If neither of the above conditions is met, the state of I/O (at access time and until CAS and RAS or OE go backto VIH) is indeterminate. OE held HIGH and WE taken LOW after CAS goes LOW result in a LATE WRITE (OE-controlled) cycle.15.Output parameter (I/O) is referenced to corresponding CAS input, I/O0-I/O7 by LCAS and I/O8-I/O15 by UCAS.
16.During a READ cycle, if OE is LOW then taken HIGH before CAS goes HIGH, I/O goes open. If OE is tied permanently LOW, a LATE
WRITE or READ-MODIFY-WRITE is not possible.17.Write command is defined as WE going low.
18.LATE WRITE and READ-MODIFY-WRITE cycles must have both tOD and tOEH met (OE HIGH during WRITE cycle) in order to ensure
that the output buffers will be open during the WRITE cycle. The I/Os will provide the previously written data if CAS remains LOWand OE is taken back to LOW after tOEH is met.
19.The I/Os are in open during READ cycles once tOD or tOFF occur.20.The first χCAS edge to transition LOW.21.The last χCAS edge to transition HIGH.
22.These parameters are referenced to CAS leading edge in EARLY WRITE cycles and WE leading edge in LATE WRITE or READ-MODIFY-WRITE cycles.
23.Last falling χCAS edge to first rising χCAS edge.
24.Last rising χCAS edge to next cycle’s last rising χCAS edge.25.Last rising χCAS edge to first falling χCAS edge.26.Each χCAS must meet minimum pulse width.27.Last χCAS to go LOW.
28.I/Os controlled, regardless UCAS and LCAS.
29.The 3 ns minimum is a parameter guaranteed by design.30.Enables on-chip refresh and address counters.
