Description
The V53C816H is a 524,288 x 16 bit high-perfor-
mance CMOS dynamic random access memory.
The V53C816H offers Fast Page mode with dual
CAS inputs. An address, CAS and RAS input ca-
pacitances are reduced to one half when the
256Kx16 DRAM is used to construct the same
memory density. The V53C816H has asymmetric
address, 10-bit row and 9-bit column.
All inputs are TTL compatible. Fast Page Mode
operation allows random access up to 512K x 16
bits, within a page, with cycle times as short as
23ns.
The V53C816H is best suited for graphics, and
buffer memory applications.
