4-Mbit SRAMs offer fast access time for radiation-hardened systems

Designed to meet the stringent radiation, size and weight requirements of space applications, two new sub-20-ns 4-Mbit SRAMs combine radiation hardened capabilities with fast access time over the full military temperature range. From the existing 3.3-V, AT60142E SRAM, Atmel Corp. has derived two new versions, the AT60142F with improved speed and power consumption, and the AT60142FT, a 5-V variant.
