Latest Patents
Shiming Song holds a patent for an SRAM-based process in memory systems. This invention is crucial for applications that require a large number of multiply-accumulate (MAC) operations, which are demanding in both computation and memory. The proposed process computes directly on a large array of data in place, effectively eliminating the expensive overhead associated with data movement. To enable parallel multi-bit MAC operations, both width- and level-modulating memory word lines are utilized. Additionally, a delay-locked loop is employed to generate fine unit pulses for driving memory word lines, while a dual-ramp Single-slope ADC is used to convert bit line outputs. The concept has been prototyped in a 180 nm CMOS test chip, consisting of four 320×64 compute-SRAMs, each supporting 128× parallel 5 b×5 b MACs with 32 5 b output ADCs, consuming 16.6 mW at 200 MHz.
