Description

CMOS dynamic random access memory. The

V53C8125H offers a combination of features: Fast

Page Mode for high data bandwidth, fast usable

speed, CMOS standby current.

and output capacitances are significantly lowered to

allow increased system performance. Fast Page

Mode operation allows random access of up to 512

columns (x9) bits within a row with cycle times as

short as 19 ns. Because of static circuitry, the CAS

clock is not in the critical timing path. The flow-

through column address latches allow address

pipelining while relaxing many critical system timing

requirements for fast usable speed. These features

make the V53C8125H ideally suited for graphics,

digital signal processing and high performance pe-

ripherals.
