Method and system for decoding a row address to assert multiple adjacent rows in a memory structure

Abstract

A memory array or structure and method for decoding a read address to facilitate simultaneous reading of successive rows. The memory includes row decoders in the form of decoding logic for enabling multiple rows of the memory structure to be read in response to a single row address. The memory structure helps to reduce the number of ports that are required for the memory structure and, thus, reduces the die area occupied by the memory structure. The row address may be divided into most significant bits and least significant bits. Further, the decoding logic may decode the most significant bits differently from the least significant bits when processing the row address. The most significant bits may be preprocessed or predecoded into a fully decoded format while the least significant bits may be decoded into a priority decoded format.
