GENERAL DESCRIPTION
The 128K x 8 Radiation Hardened Static RAM is a high
performance 131,072 word x 8-bit static random access
memory with industry-standard functionality. It is fabricated
with Honeywell鈥檚 radiation hardened technology, and is
designed for use in systems operating in radiation environ-
ments. The RAM operates over the full military temperature
range and requires only a single 5 V
鹵
10% power supply. The
RAM is wire bond programmable for either TTL or CMOS
compatible I/O. Power consumption is typically less than 25
mW/MHz in operation, and less than 5 mW in the low power
disabled mode. The RAM read operation is fully asynchro-
nous, with an associated typical access time of 15 ns at 5V.
Honeywell鈥檚 enhancedSOI RICMOS鈩V (Radiation Insen-
sitive CMOS) technology is radiation hardened through the
use of advanced and proprietary design, layout and process
hardening techniques. The RICMOS鈩?IV process is an
advanced 5-volt, SIMOX CMOS technology with a 150 脜
gate oxide and a minimum feature size of 0.7
碌m
(0.55
碌m
effective gate length鈥擫
eff
). Additional features include
Honeywell鈥檚 proprietary SHARP planarization process, and
a lightly doped drain (LDD) structure for improved short
channel reliability. A 7 transistor (7T) memory cell is used for
superior single event upset hardening, while three layer
metal power bussing and the low collection volume SIMOX
substrate provide improved dose rate hardening.
