  • Multi-ported memory architecture using single-ported RAM
    Patent number: 6212607
    Abstract: A memory device (201) having left (203) and right (204) ports for communicating with left (205) and right (206) electronic devices, includes memory banks (401-0˜401-7), semaphore logic (302), and port coupling circuitry (403, 404, 405-0˜405-7, 406-0˜406-7, 407-0˜407-7). The semaphore logic generates bank access grant signals (313, 314) on a first received basis in response to bank access requests from the left and right electronic devices, and the port coupling circuitry couples selected memory banks to the left and right ports in response to the bank access grant signals. Also included in the memory device are mail-box registers (2500-0L˜2500-3L, 2500-0R˜2500-3R), interrupt generating circuitry (2514-0L˜2514-3L, 2514-0R˜2514-3R, 2900, 3000, 307, 308), and interrupt status and cause registers (3101L˜3102L, 3101R˜3102R, 3301L˜3302L, 3301R˜3302R).
