The HX6356-BNT Radiation Hardened Static RAM is a high performance 32,768 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 systems operating in harsh, transient radiation environments. The RAM operates over the full military temperature range and requires only a single 5 V ±10% power supply. The RAM is available with either TTL or CMOS compatible I/O. Power consumption is typically less than 15 mW/MHz in operation, and less than 5 mW when de-selected. The RAM read operation is fully asynchronous, with an associated typical access time of 14 ns at 5V.
Honeywell’s enhanced SOI RICMOS™IV (Radiation Insensitive CMOS) technology is radiation hardened through the use of advanced and proprietary design, layout and process hardening techniques. The RICMOS™ IV process is a 5-volt, SIMOX CMOS technology with a 150 Å gate oxide
and a minimum drawn feature size of 0.75 µm (0.6 µmeffective gate length—Leff). Additional features include tungsten via plugs, 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.
