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 ). Additional features include tungsten via plugs,
eff
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.
