Method for monitoring a data memory

摘要

A method is described for monitoring a data memory in which an error detection method is used to detect and/or correct incorrect data words stored in memory lines of the data memory, an address of the data memory at which a data word evaluated as incorrect by the error detection method is stored being written to an auxiliary memory and being made available to a checking program.

主权项

1. A method for monitoring a data memory, comprising:
applying, by processing circuitry, an error detection method to the data memory to at least one of detect and correct incorrect data words stored in memory lines of the data memory; for each of at least a subset of data words evaluated as incorrect by the error detection method, writing, by the processing circuitry and to an auxiliary memory, an address of the data memory at which the respective data word is stored; and applying, by the processing circuitry, a checking program that, when at least one of the data memory addresses is stored in the auxiliary memory, cyclically runs through the auxiliary memory on a schedule that is independent of the application of the error detection method, to perform an error detection for the data memory addresses stored in the auxiliary memory.
