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’s radiation hardened technology, and is

designed for use in low voltage systems operating in radiation

environments. The RAM operates over the full military

temperature range and requires only a single 3.3 V

± 0.3V

power supply. The RAM is compatible with JEDEC standard

low voltage CMOS I/O. Power consumption is typically less

than 9 mW/MHz in operation, and less than 2 mW when de-

selected. The RAM read operation is fully asynchronous, with

an associated typical access time of 32 ns at 3.3 V.

Honeywell’s enhanced SOI RICMOS™ IV (Radiation Insensi-

tive CMOS) technology is radiation hardened through the use

of advanced and proprietary design, layout and process

hardening techniques.TheRICMOS™IVlow power process is

a SIMOX CMOS technology with a 150 Å gate oxide and a

minimum drawn feature size of 0.7

µm (0.55 µm effective gate

length—L

Honeywell’s 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.
