Description
The V59C1512(404/804/164)Q is a four bank DDR
DRAM organized as 4 banks x 32Mbit x 4 (404), 4 banks x
16Mbit x 8 (804), or 4 banks x 8Mbit x 16 (164). The
V59C1512(404/804/164)Q achieves high speed data
transfer rates by employing a chip architecture that
prefetches multiple bits and then synchronizes the output
data to a system clock.
The chip is designed to comply with the following key
DDR2 SDRAM features:(1) posted CAS with additive la-
tency, (2)write latency=read latency-1, (3)Off-chip Driv-
er(OCD) impedance adjustment, (4) On Die Termination.
All of the control, address, circuits are synchronized
with the positive edge of an externally supplied clock. I/O
s are synchronized with a pair of bidirectional strobes
(DQS, DQS) in a source synchronous fashion.
Operating the four memory banks in an interleaved
fashion allows random access operation to occur at a
higher rate than is possible with standard DRAMs. A se-
quential and gapless data rate is possible depending on
burst length, CAS latency and speed grade of the device.
