摘要： A system and method for disabling access to individually addressable regions of an array of non-volatile memory. In response to receiving an initial valid command, a process for disabling access to the defective portions of the array of non-volatile memory is initiated in addition to executing the initial valid command. One implementation provides receiving a memory command and determining whether an indicator has been set. In response to the indicator not being set, access to defective regions of the array of non-volatile memory is disabled in addition to executing the memory command. The indicator is also set to prevent the disabling process from being performed in response to receipt of subsequent memory commands.

摘要： A flash memory device programs cells in each row in a manner that minimizes the number of programming pulses that must be applied to the cells during programming. The flash memory device includes a pseudo pass circuit that determines the number of data errors in each of a plurality of subsets of data that has been programmed in the row. The size of each subset corresponds to the number of read data bits coupled from the memory device, which are simultaneously applied to error checking and correcting circuitry. During iterative programming of a row of cells, the pseudo pass circuit indicates a pseudo pass condition to terminate further programming of the row if none of the subsets of data have a number of data errors that exceeds the number of data errors that can be corrected by the error checking and correcting circuitry.

摘要： A memory device to perform an erase operation algorithm that specifically deals with different types of defects in a memory array. The memory array of one embodiment of the present invention has primary and redundant elements. A register is used for each redundant element to store the address of a defective primary element and an error code that indicates the type of defect in the defective primary element. Control circuitry is used to control memory operations to the memory array. The control circuitry performs an erase operation algorithm that is specific to an error code when a defective primary element is addressed during an erase operation.

摘要： A memory device includes a plurality of memory dies, each having an assigned address. A register on each die is reset on power-up. Boot data is loaded as part of the initialization routine. If the boot data includes a reconfigured command, that command is loaded into the register. A signal is generated if the register has been altered by the stored reconfigured command. If the signal indicates that the register has not been altered, a received command is executed without reconfiguration. If the signal indicates that the register contains something other than the reset state, the contents of the register are compared with the received command. If the received command and the register contents are equal, the reconfigured command is executed.

摘要： A memory device uses data compression to read data from an array of the memory during testing. The compressed data is either a logic one, logic zero or tri-state, depending upon the data read from the array. Output drivers of the memory are placed in a tri-state condition in response to a detected read error. Non-compressed internal I/O lines are used during testing to provide control signals to the driver circuitry to selectively place drivers in the tri-state mode. Once a tri-state is detected four columns of memory cells can be replaced with four columns of redundant memory cells without requiring additional non-compressed testing.
