Abstract

See full text

A computing-in-memory circuitry includes multiple digital-to-analog converters, multiple computing arrays, and multiple charge processing networks. The digital-to-analog converters convert external data into input data and the digital-to-analog converters are connected in series with a corresponding plurality of output capacitor pairs. The computing arrays receive the input data from both ends and execute a computation to output a first computing value. The charge processing networks receive and accumulate the first computing values over a predetermined time interval through switching pairs in series with the output capacitor pairs. The charge processing networks evenly distribute charges of the first computing value to selected output capacitor pairs and compare voltage differences between two ends of the output capacitor pairs to output a second computing value.
