摘要： Electronic systems and methods of operating memory devices are provided. In one such embodiment, a memory device receives an external address that addresses a non-defective memory block of a sequence of memory blocks of the memory device in place of a defective memory block of the sequence of memory blocks such that the non-defective memory block replaces the defective memory block. The non-defective memory block is proximate non-defective memory block following the defective memory block in the sequence of memory blocks that is available to replace the defective memory block.

摘要： Controllers and memory devices are provided. In an embodiment, a controller is configured to address a non-defective column of memory cells of a memory device in place of a defective column of memory cells of the memory device in response to receiving an address of the defective column of memory cells from the memory device. In another embodiment, a memory device has columns of memory cells and is configured to receive an external address that addresses a non-defective column of memory cells of a sequence of columns of memory cells of the memory device in place of a defective column of memory cells of the sequence of columns of memory cells such that the non-defective column replaces the defective column. The non-defective column is a proximate non-defective column following the defective column in the sequence of columns that is available to replace the defective column.

摘要： Methods for sensing, method for programming, memory devices, and memory systems are disclosed. In one such method for sensing, a counting circuit generates a count output and a translated count output. The count output is converted into a time varying voltage that biases a word line coupled to memory cells being sensed. Target data for each memory cell is stored in a data cache associated with that particular memory cell. When it is detected that a memory cell has turned on, the translated count output associated with the count output that is indicative of the voltage level that turned on the memory cell is compared to the target data. The comparison determines the state of the memory cell.

摘要： In erasing a memory block of memory cells, a semiconductor tub that contains a memory block to be erased can be biased with a high, positive voltage. The control gates of the memory cells that make up the memory block can be biased with a negative voltage. An erase verification can then be performed to determine if the memory block has been successfully erased. If the memory block has not been erased, the erase operation of biasing the tub with the positive voltage and the control gates with the negative voltage can be repeated until the erase verification is successful.
