Millennium – Radiation-Hardened SRAM

The Millennium high-speed SRAM family is the fourth generation in a long line of BAE Systems radiation-hardened static RAM products.

The SRAM die is a high-performance 524,288 word x 8-bit static random-access memory with industry-standard functionality. It is designed by BAE Systems for use in systems operating in strategic radiation environments and commercial space applications.

The SRAM is offered in three configurations: a 512K x 8 single-chip modules, a 512K x 32 multi-chip module, and a 512K x 40 multi-chip module. The RAM operates over the full military temperature range and requires a single 2.5 V ±5% power supply. The SRAM also can be operated with dual voltage to allow interfacing with 3.3V I/O. Power consumption is typically less than 25mW/MHz in operation and less than 15 mW in the low-power disabled mode for the single-chip version. The SRAM read operation is fully asynchronous, with an associated typical access time of 15 nanoseconds.

BAE Systems’ products are radiation-hardened through the use of advanced and proprietary design, layout, and process hardening techniques. Millennium has a total dose tolerance of greater than 200 krads and an upset rate of  less than 1E-10 upsets per bit day.
