Description
The V53C8125H is a high speed 131,072 x 8 bit
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.
All inputs and outputs are TTL compatible. Input
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.
