Abstract

Die cost economics require high-density mem- ories to utilize array redundancy, which invokes the necessity to physically locate defective memory cells in an array, usually referred to as bitmapping. For a typical memory, bitmapping capability is an inher- ent fact, since memory locations and the data therein are externally accessable. In the case ofan imbedded memory, however, data is supplied for internal DSP, a design technique which allows data to be externally accessable must be implemented.
