  • Ultra-low-power variation-tolerant radiation-hardened cache design
    Patent number: 8605516
    Abstract: A random access memory (RAM) cell provides a control section and a storage section coupled to the storage section. The storage section includes complementary metal-oxide semiconductor (CMOS) transistors and the storage section is read by precharging the control section to a virtual drain voltage.
    Type: Grant
