Abstract

An in-memory computation (IMC) system includes an in-memory computation circuit formed by a first phase change memory (PCM) array configured to store the computational weights for an in-memory computation operation. A data storage circuit is formed by a second PCM array configured to store backup data for the computational weights for the in-memory computation operation. The first PCM array includes PCM cells made of a phase change material provided by a first GST alloy, and the second PCM array includes PCM cells made of a phase change material provided by a second GST alloy different from the first GST alloy. A control circuit operates to read the backup data from the second PCM array and write to the first PCM array to refresh the computational weights for the in-memory computation operation from the backup data.
