Description
The V43658R04VATG-10PC memory module is
organized 8,388,608 x 64 bits in a 168 pin dual in
line memory module (DIMM). The 8M x 64 memory
module uses 4 Mosel-Vitelic 8M x 16 SDRAM. The
x64 modules are ideal for use in high performance
computer systems where increased memory
density and fast access times are required.

tRC. Input signals are changed one time during tCK.

Notes:
1. The specified values are valid when addresses are changed no more than once during t CK(min.) and when No
Operation commands are registered on every rising clock edge during t RC(min). Values are shown per module
bank.
2. The specified values are valid when data inputs (DQ’s) are stable during t RC(min.).
3. All AC characteristics are shown for device level.
An initial pause of 100 µs is required after power-up, then a Precharge All Banks command must be given fol-
lowed by 8 Auto Refresh (CBR) cycles before the Mode Register Set Operation can begin.
4. AC timing tests have V IL = 0.4V and V IH = 2.4V with the timing referenced to the 1.4V crossover point. The
transition time is measured between V IH and VIL. All AC measurements assume tT = 1 ns with the AC output load
circuit shown. Specific tac and toh parameters are measured with a 50 pF only, without any resistive termination
and with a input signal of 1V / ns edge rate between 0.8V and 2.0V.

5. If clock rising time is longer than 1 ns, a time (t T/2 -0.5) ns has to be added to this parameter.
6. Rated at 1.5V
7. If t T is longer than 1 ns, a time (tT -1) ns has to be added to this parameter.
8. Any time that the refresh Period has been exceeded, a minimum of two Auto (CBR) Refresh commands must be
given to “wake-up” the device.
9. Self Refresh Exit is a synchronous operation and begins on the 2nd positive clock edge after CKE returns high.
Self Refresh Exit is not complete until a time period equal to t RC is satisfied once the Self Refresh Exit command
is registered.
10. Referenced to the time which the output achieves the open circuit condition, not to output voltage levels.
11. tDAL is equivalent to t DPL + tRP.
