摘要:
Decoding and decoder circuits in memory devices are disclosed. Array lines are biased or floated as memory device operations are performed in the memory device. In at least one embodiment, a decoder circuit includes complementary devices to bias array lines or float array lines in a memory device while particular memory device operations are performed.

Memory devices adapted to repair single unprogrammable cells during a program operation, and to repair columns containing unprogrammable cells during a subsequent erase operation. Programming of such memory devices includes determining that a single cell is unprogrammable and repairing the single cell, and repairing a column containing the single cell responsive to a subsequent erase operation.

Command signal management methods and circuits in memory devices are disclosed. Command signals are selectively passed and blocked to enforce safe operating characteristics within a memory device. In at least one embodiment, a command signal management circuit is configured to selectively block a command signal while a memory device operation is being performed. In at least one other embodiment, one or more command blocking circuits are configured to selectively pass and block one or more command signals generated by a memory access device coupled to the memory device while a memory device operation is being performed in the memory device.
摘要:
Block-row decoders, memory block-row decoders, memories, methods for deselecting a decoder of a memory and methods of selecting a block of memory are disclosed. An example memory block-row decoder includes a plurality of block-row decoders, each of the block-row decoders having a decoder switch tree. Each block-row decoder is configured to bias a block select switch of the decoder switch tree with a first voltage while the block-row decoder is deselected and further configured to bias decoders switches of the decoder switch tree that are coupled to the block select switch with a second voltage while the block-row decoder is deselected, the second voltage less than the first voltage. An example method of deselecting a decoder of a memory includes providing decoder signals having different voltages to decoder switches from at least two different levels of a decoder switch tree while the decoder is deselected.
摘要:
A non-volatile memory may have memory portions, such as blocks or other granularities of units of memory, which may fail in actual use. These defective portions can be replaced with other portions which may, in some cases, be of corresponding size. In some embodiments, defects may be detected using a current sensor which detects the current drawn in actual operation. If an excessive current is drawn, this may be detected, the defective unit deactivated, and a replacement provided in its stead. This may result in the repair of a defect with little inconvenience to the user in some embodiments.

Apparatus and methods of operating memory devices are disclosed. In one such method, a first portion of the data states of memory cells are determined and transferred from a memory device while continuing to determine remaining portions of data states of the same memory cells. In at least one method, a data state of a memory cell is determined during a first sense phase and is transferred while the memory cell experiences additional sense phases to determine additional portions of the data state of the memory cell.
摘要:
A nonvolatile memory device has a dedicated serial programming port to provide a data path to memory storage. A dedicated power pin supplies power for the programming port to receive data and provide storage in the nonvolatile memory while a power pin for normal device operation is not powered.
