White Electronic Designs
4M x 16 Bits x 4 Banks Synchronous DRAM
FEATURES
DESCRIPTION
The WED416S16030Ais 268,435,456 bits of synchronous
high data rate DRAM organized as 4 x 4,196,304 words x
16 bits. 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 lengths and programmable latencies
allow the same device to be useful for a variety of high
bandwidth, high performance memory system applica-
tions.
