METHOD AND APPARATUS FOR INCORPORATING BLOCK REDUNDANCY IN A MEMORY ARRAY
摘要
An integrated circuit memory array includes alternating first and second types of memory blocks, each memory block including respective array lines shared with a respective array line in an adjacent memory block. The array lines of a defective block of one type are mapped into a spare block of the same type. The array lines of a first adjacent block which are shared with array lines of the defective block, and the array lines of a second adjacent block which are shared with array lines of the defective block, are mapped into a second spare block of the other type, thereby mapping the defective block and portions of both adjacent blocks into just two spare blocks.
