32k X 8 Rom-soi

The 32K x 8 Radiation Hardened ROM is a high perform- ance 32,768 word x 8-bit read only memory with industry- standard functionality. It is fabricated with Honeywells radiation hardened technology, and is designed for use in systems operating in radiation environments. The ROM operates over the full military temperature range and re- quires only a single 5 V 10% power supply. The ROM 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 ROM operation is fully asynchronous, with an associated typical access time of 14 ns. Honeywells enhanced SOI RICMOSIV (Radiation Insen- sitive CMOS) technology is radiation hardened through the use of advanced and proprietary design, layout, and pro- cess hardening techniques. The RICMOS IV process is a 5-volt, SIMOX CMOS technology with a 150 Gate oxide and a minimum drawn feature size of 0.75 m (0.6 m effective Gate lengthLeff ). Additional features include tungsten via plugs, Honeywells proprietary SHARP pla- narization process, and a lightly doped drain (LDD) struc- ture for improved short channel reliability. By Unkown
