Description
The V53C8258L is a ultra high speed 262,144 x
8 bit CMOS dynamic random access memory. The
V53C8258L offers a combination of features: Page
Mode with Extended Data Output for high data
bandwidth, and Low CMOS standby current.
All inputs and outputs are TTL compatible. Input
and output capacitances are significantly lowered
to allow increased system performance. Page
Mode with Extended Data Output operation allows
random access of up to 512 (x8) bits within a row
with cycle times as fast as 27 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. The V53C8258L is
ideally suited for graphics, digital signal processing
and high-performance computing systems.
