摘要
A 32-kb macro containing an eight-transistor soft error robust SRAM cell with differential read and write capabilities is presented. The 8T cell does not have dedicated access transistors, and its quad-latch configuration stores data on four interlocked storage nodes. The macro was designed in a 65-nm CMOS process. The cell demonstrates excellent read data stability down to 0.55 V and is well suited for low-voltage, low-power applications. Neutron radiation testing on the macro exhibits at least 15x improvement in Failure in Time (FIT) rate compared with the conventional 6T SRAM cell in 65-nm CMOS technology.
