Abstract

See full text

Mapping an address for memory access in a memory system into a combination address that includes a memory bank identifier and a memory bank internal address. The address is partitioned into a first portion, and a second portion. The memory bank identifier is determined by performing a look-up operation in a look-up matrix, in which a look-up matrix row is determined by the value of the first portion, and a look-up matrix column is determined by the value of a binary number with two or more bits formed by applying a parity function to two or more respective sub-portions of the second portion. The memory bank internal address is derived based on the second portion of the address.
