A new reading mode based on balanced pre-charging and group decoding

Abstract

In this paper, the balanced pre-charging and group decoding are presented to realize in-memory computing which can achieve continuous read operations after only one pre-charge operation. Compared with the analog computing of multi-row parallel reading, this structure adopts digital domain computing, which improves the accuracy of computing; compared with the non multi-row in-memory computing, it improves the computation speed. The simulation results of noise margin, read times, and read speed show that the proposed method can improve memory performance. The maximum stability can be improved by 13.8%, the read speed can be improved by 75%, and the power consumption can be reduced by 11.58%. Besides, it can be widely used in a variety of memory structures. The proposed method is applied to the existing in-memory computing structures to verify the effectiveness.
