Description
The V53C16258L is a 262,144 x 16 bit high-
performance CMOS dynamic random access
memory. The V53C16258L offers Page mode with
Extended Data Output. An address, CAS and RAS
input capacitances are reduced to one quarter
when the x4 DRAM is used to construct the same
memory density. The V53C16258L has symmetric
address and accepts 512 cycle 8ms interval.
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 V53C16258L is ideally suited for a wide
variety of high performance portable computer
systems and peripheral applications.
