VDS8608A8A
Synchronous DRAM
8M x 8 Bit x 4 Banks
General Description
The VDS8608A8A are four-bank Synchronous
DRAMs organized as 8,388,608 words x 8 bits x 4
banks.
Synchronous design allows precise cycle control
with the use of system clock I/O transactions are
possible on every clock cycle.
Range of operating frequencies, programmable
burst length and programmable latencies allow the
same device to be useful for a variety of high
bandwidth high performance memory system
applications
Features
JEDEC standard LVTTL 3.3V power supply
MRS Cycle with address key programs
-CAS Latency (2 & 3)
-Burst Length (1,2,4,8,& full page)
-Burst Type (sequential & Interleave)
4 banks operation
All inputs are sampled at the positive edge of
the system clock
Burst Read single write operation
Auto & Self refresh
DQM for masking
8192 Refresh Cycles
