Description
The V53C818H is a 524,288 x 16 bit high-
performance CMOS dynamic random access
memory. The V53C818H offers Page mode
operation with Extended Data Output. An address,
CAS and RAS input capacitances are reduced to
one half when the 256K x 16 DRAM is used to
construct the same memory density. The
V53C818H has asymmetric address, 10-bit row and
9-bit column.
All inputs are TTL compatible. EDO Page Mode
operation allows random access up to 512 x 16 bits,
within a page, with cycle times as short as 15ns.
The V53C818H is ideally suited for graphics,
digital signal processing and high performance
peripherals.
