Abstract
A programmable memory includes a memory matrix (34) with a row decode circuit (36) and a column decode circuit (48) operable in the program mode to select one of the memory elements in the memory matrix (34). A current boost circuit (50) is operable to provide increased current to the selected cell such that selection of the cell opens the fuse associated therewith to change the logic state. The pins associated with the column and row addresses have multiple mode functions such that in the normal operating mode they can be assigned other tasks and in the programming mode are utilized primarily for addressing of the memory cells.
