Abstract

Official abstract text for this publication.

A method and apparatus for managing memory in an electronic system is described. The method includes determining a failure in an element of the memory array that is repairable by a redundant element. The method may further include using a latch to identify the redundant element. The method may also include that upon an event, using a value in the latch in an eFuse which subsequently selects the redundant element.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for managing memory in an electronic system comprising: a memory array containing a redundant element that may be activated using either a latch or an eFuse; a logic module, that is adapted to, upon the determination of a failure in an element of the memory array that is repairable by a redundant element uses a latch to identify the redundant element, and upon an event, transferring a value from the latch to the eFuse, which subsequently selects…
