    摘要: A multiple purpose bus for a flash memory device that allows six sets of data signals to utilize the bus. 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: A variable sector size for a flash memory device is disclosed. The total available memory of the flash memory device is divided into sub-units. Each sub-unit has a pre-decoder coupled with it to enable operations on the memory within that sub-unit. A sector size control register is coupled with pre-decoder enabling logic which is coupled with the pre-decoders. The sector size control register and pre-decoder enabling logic determines how many pre-decoders, and therefore how many sub-units, are activated at a given time for a given memory operation.

    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.
