Methods and apparatuses for in-system field repair and recovery from memory failures
Abstract:
In a particular embodiment, a device includes memory address remapping circuitry and a remapping engine. The memory address remapping circuitry includes a comparison circuit to compare a received memory address to one or more remapped addresses. The memory address remapping circuitry also includes a selection circuit responsive to the comparison circuit to output a physical address. The physical address corresponds to a location in a random-access memory (RAM). The remapping engine is configured to update the one or more remapped addresses to include a particular address in response to detecting that a number of occurrences of errors at a particular location satisfies a threshold.
