Abstract
Certain aspects of the present disclosure provide techniques for performing compute in memory (CIM) computations. A device comprises a CIM module configured to apply analog weights to input data using multiply-accumulate operations to generate an output. The device further comprises a digital weight storage unit configured to store digital weight references, wherein a digital weight reference corresponds to an analog weight of the analog weights. The device also comprises a device controller configured to program the analog weights to the CIM module, cause the CIM module to process the input data, and reprogram one or more analog weights that are degraded. The digital weight references in the digital weight storage unit are populated with values from a host processing device. Degraded analog weights in the CIM module are reprogrammed based on the corresponding digital weight references from the digital weight storage unit without reference to the host processing device.
