Abstract :
A register file read-out method that relies on differential current-mode sensing, while using single-ended bit lines, is presented. This method improves noise immunity, access, and cycle time compared to dynamic approaches. A 34×64-bit, 10R/6W, write-through register file is implemented in 0.11 μm, 1.2 V CMOS with an access time of 1.07 ns and dissipation of 133 mW at 500 MHz.
