Description
The V54C333322V is a 33,554,432 bits synchro-
nous high data rate DRAM organized as 2 x
524,288 words by 32 bits. The device is designed to
comply with JEDEC standards set for synchronous
DRAM products, both electrically and mechanically.
Synchronous design allows precise cycle control
with the system clock. The CAS latency, burst
length and burst sequence must be programmed
into device prior to access operation.
