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”.
