Abstract
There is disclosed a memory capable of storing a present value and at least one past value of a variable accessible by a first memory address. The memory comprises a memory block comprising R rows of memory cells and a row address decoder for decoding the first memory address. During a read operation, the row address decoder causes data to be retrieved from a row in which data stored to the first memory address was last written. During a write operation, the row address decoder causes data to be stored in a next-sequential row following the last-written row.
