    摘要: An improved non-volatile erase block memory device apparatus and method is described that incorporates an improved addressing scheme to provide for extended addressing allowing redundant erase blocks that are not utilized to repair general use erase blocks of the main memory array to be accessed and utilized as additional storage space by an end user. The additional storage space formed by the unused redundant erase blocks and the specified storage space of the main memory array is presented to the end user as a single contiguous address space. Additionally, the redundant erase blocks can be utilized to repair any damaged erase block in the memory array of the non-volatile erase block memory or Flash memory device regardless of bank placement.

    摘要: A target memory cell of a memory device is programmed by applying a programming voltage to a word line that includes the target memory cell, determining whether the target memory cell is programmed, and increasing the programming voltage by a step voltage if it is determined that the target memory cell is not programmed. An initial programming voltage and the step voltage are each selectable after fabrication of the memory device.

    摘要: A scheme for defective memory column or row substitution is disclosed which uses a programmable look-up table to store new addresses for column selection when certain column or row addresses are received. The new addresses are loaded into a programmable fuse latch each time an address transition is detected in the input address.

    摘要: A non-volatile memory is described that utilizes a cache read mode of operation, where a next page of memory is being read/sensed from the memory array by the sense amplifiers while a previously read page of memory is being read from the memory I/O buffer, wherein the next page is user selected. This random cache read mode allows for a memory with a random page read capability, in which the address of the next page of data to be read is user selectable, which benefits from the low latency of a cache read mode of operation due to concurrent data sensing and data I/O.

    摘要: The method for reducing program disturb in a flash memory array biases a selected wordline at a programming voltage. One of the unselected wordlines, closer to array ground than the selected wordline, is biased at a voltage that is less than Vpass. The memory cells on this unselected wordline that are biased at this voltage block the gate induced drain leakage from the cells further up in the array. The remaining unselected wordlines are biased at Vpass. In another embodiment, a second source select gate line is added to the array. The source select gate line that is closest to the wordlines is biased at the voltage that is less than Vpass in order to block the gate induced drain leakage from the array.
