Description
The V826632K24SA memory module is
organized 33,554,432 x 64 bits in a 184 pin memory
module. The 32M x 64 memory module uses 8
ProMOS 32M x 8 DDR SDRAM. The x64 modules
are ideal for use in high performance computer
systems where increased memory density and fast
access times are required.

Notes: 1. This calculation accounts for tDQSQ(max), the pulse width distortion of on-chip circuit and jitter.
2. Data sampled at the rising edges of the clock : A0~A11, BA0~BA1, CKE, CS, RAS, CAS, WE.
3. For command/address input slew rate >=1.0V/ns
4. For command/address input slew rate >=0.5V/ns and <1.0V/ns
5. CK, CK slew rates are >=1.0V/ns
6. These parameters guarantee device timing, but they are not necessarily tested on each device, and they may be guaranteed
by design or tester correlation.
7. Data latched at both rising and falling edges of Data Strobes(DQS) : DQ, DM
8. Minimum of 200 cycles of stable input clocks after Self Refresh Exit command, where CKE is held high, is required to complete
Self Refresh Exit and lock the internal DLL circuit of DDR SDRAM.
