General Description

The HT6116-70 is a 16384-bit static random

access memory. It is organized with 2048 words

of 8 bits in length, and operates with a single 5V

power supply. The IC is built with a high per-

formance CMOS 0.8µm process in order to ob-

tain a low standby current and high reliability.

The IC contains six-transistor full CMOS mem-

ory cells and TTL compatible inputs and out-

puts, which are easily interface with common

system bus structures. The Data bus of the

HT6116-70 is designed as a tri-state type. The

IC is in the standby mode if the CS pin is set to

“high”.
