Classification of Computing in Memory Principles - Digital Computing in Memory Vs. Analog Computing

As a new type of architecture, the integration of data storage and computation is expected to break through the bottleneck of arithmetic power and power consumption.computing in memorycan be divided into two categories: analog and digital. In the next section, we will focus on digitalcomputing in memoryand analogcomputing in memoryand their advantages and disadvantages.

I. Digital in-deposit calculations

Digital computing in memory utilizes all-digital circuits to perform computations, which refers to the integration of digital logic into in-store computing, and is capable of integrating bit-by-bit digital product-accumulation operations directly into memory arrays. Since digitalcomputing in memoryis structurally well supported for multiply-accumulate computation, it has great potential for application in computing scenarios where neural networks are in demand, such as speech processing in smartwatches and Bluetooth headsets, neural network computing acceleration in smartphones, and model ...
