  • Clock switching circuitry for avoiding conflict of data handling occuring in a memory
    Patent number: 6597627
    Abstract: Clock switching circuitry includes a memory having a plurality of storage locations of a particular address each and configured to allow data to be written in and read out at the same time. The circuitry further includes a write pointer, a read pointer, a synchronizing circuit, a conflict detector, and a conflict avoiding circuit. The circuitry detects a conflict with high reliability and facilitates design using a CAD (Computer Aided Design) tool.
    Type: Grant
