Abstract
A method for generating a memory of various sizes and configurations uses a plurality of banks. The banks are selected to meet memory requirements and size constraints and are arranged in an orthogonal array. Critical paths are minimized using commercially available software.
Claims7
A method of designing an integrated circuit memory architect wherein the memory architecture has a required memory capacity and determinable physical boundaries, the method comprising:
- defining a set of individual memory bank designs such that each individual memory bank design has a set of characteristics that is different than the set of characteristics of other individual memory bank designs;
- tiling selected individual memory bank designs to provide a memory array architecture comprising rows and columns of memory banks such that adjacent memory banks in the memory array architecture have matching dimensions along a common boundary and wherein address signals are routed between adjacent memory banks;
- and
- designing control circuitry to operationally couple with the memory banks, wherein the control circuitry is configured to generate addressing signals for selecting address locations from within the memory banks.
