    摘要: A simultaneous operation flash memory capable of providing double protection to An OTP sector. The preferred simultaneous operation flash memory comprises an OTP write-protect CAM, which is in a programmed state if the OTP sector is write-protected. In addition, the preferred simultaneous flash memory further includes an OTP sector lock CAM that is electrically connected with the OTP write-protect CAM. The OTP sector lock CAM is used to lock the OTP write-protect CAM in the programmed state, which, in turn, will designate the OTP sector as read only.

The multiple purpose bus includes sixteen circuit lines that extend from one end of the memory device to another end of the memory device. Control signals that correspond to each set of data signals couple the sets of data signals to the circuit lines. A grounding circuit is provided that couples the circuit lines to a ground when none of the sets of data signals are utilizing the multiple purpose bus.

    摘要: The present invention discloses sector-based redundancy that is capable of making repairs using a plurality of redundant columns of memory cells in a dual bank memory device during simultaneous operation. The simultaneous operation memory device includes a plurality of redundant blocks that can be configured to be located in an upper bank or a sliding lower bank. The redundant blocks are comprised of sectors and each sector contains columns of memory cells. During simultaneous operation, the memory device is capable of reading the columns of memory cells in one bank and writing columns of memory cells in the other bank at the same time. In addition, the simultaneous operation memory device uses sector-based redundancy to repair columns of memory cells that are defective in one bank by electrically exchanging them with redundant columns of memory cells and, at the same time, repair columns of memory cells that are defective in the other bank. The dual bank sector-based redundancy includes a plurality of address CAM circuits that are configurably associated with the redundant blocks based on the bank location of the redundant blocks. The address CAM circuits are configured by a redundancy CAM read drain decoder circuit.
