Automatic recovery of memory operability in microprocessor based control system

Abstract

The problem of increasing the coefficient of technical readiness of memory module, the value of which increases with decreasing of control system recovery time in case of failure of its constituent units, is solved. The proposed structure of the memory module with built-in self-test and restore functionality that will allow auto-replacing bits of data of the main memory cell array, in which there have been failures in the data output from the spare memory cell array. Automatic reconfiguration of the memory module when a fault is detected provides the proposed hardware and software.
