DESCRIPTION

RC7C1024RHS SRAM is a low voltage, high performance, asynchronous, radiation-hardened 128kbit x8 memory device using six transistor (6T) memory cells with Miller Capacitors. A standard 0.18u CMOS 6 metals technology process has been used to implement RC7C1024RHS with a dedicated robust rad-hard by design (RHBD) approach using ELT transistors, enhanced guard rings and ELT ESD pads.

RC7C1024RHS has been specifically designed for applications with TID requirements in range from 100krad (Si) to 300krad (Si) such as LEO, MEO and GEO.
