Description
The V54C3256(16/80/40)4VD*I is a four bank
Synchronous DRAM organized as 4 banks x 4Mbit
x 16, 4 banks x 8Mbit x 8, or 4 banks x 16Mbit x 4.
The
V54C3256(16/80/40)4VD*I
achieves
high
speed data transfer rates up to 166 MHz by employ-
ing a chip architecture that prefetches multiple bits
and then synchronizes the output data to a system
clock
All of the control, address, data input and output
circuits are synchronized with the positive edge of
an externally supplied clock.
Operating the four memory banks in an inter-
leaved fashion allows random access operation to
occur at higher rate than is possible with standard
DRAMs. A sequential and gapless data rate of up to
166 MHz is possible depending on burst length,
CAS latency and speed grade of the device.
