Apparatus and methods are provided for operating a non-volatile memory module. In an example, a method can include filling a first plurality of pages of a first non-volatile memory with first data from a first data lane that includes a first volatile memory device, and filling a second plurality of pages of the first non-volatile memory device with second data from a second data lane that includes a second volatile memory device. In certain examples, the first plurality of pages does not include data from the second data lane.

Exemplary methods, apparatuses, and systems include determining that data in a group of memory cells of a first memory device is to be moved to a spare group of memory cells. The group of memory cells spans a first dimension and a second dimension that is orthogonal to the first dimension and the spare group of memory cells also spans the first dimension and the second dimension. The data is read from the group of memory cells along the first dimension of the group of memory cells. The data is written to the spare group of memory cells along the second dimension of the spare group of memory cells.

A nonvolatile memory device includes a memory cell array and a bad block remapping circuit. The memory cell array includes a first mat and a second mat that are paired with each other. The first mat includes a plurality of first memory blocks. The second mat includes a plurality of second memory blocks. A first selection memory block among the plurality of first memory blocks and a second selection memory block among the plurality of second memory blocks are accessed based on a first address. The bad block remapping circuit generates a first remapping address based on the first address when it is determined that the first selection memory block is defective. A first remapping memory block among the plurality of first memory blocks and the second selection memory block are accessed based on the first remapping address.

A solid-state drive (SSD) is configured for dynamic resizing. When the SSD approaches the end of its useful life because the over-provisioning amount is nearing the minimum threshold as a result of an increasing number of bad blocks, the SSD is reformatted with a reduced logical capacity so that the over-provisioning amount may be maintained above the minimum threshold.

A data storage apparatus includes a nonvolatile memory device and a controller configured to determine whether or not one or more addresses of defective bit lines are included in an address of a write data to be written into the nonvolatile memory device or an address of a read data read from the nonvolatile memory device, and write the write data or read the read data by skipping the defective bit lines based on a determination result.

摘要:
A memory is released for use without pre-verification of its memory blocks as being defect free. Some memory blocks are subjected to a verification process when the computer memory is in use in order to verify a minimum number of memory blocks required for high performance program operation as being defect free. The verification process continues as the computer memory is in use in order to maintain the minimum number of memory blocks required for high performance operation in the verified defect free state. A verification mode of either no verification, delayed verification, or immediate verification is applied to memory blocks used for regular performance program operation. Delayed verification is maintained until an ability to recover the stored data is going to be lost. Immediate verification can be performed using bit error rate analysis. Some verification processes are performed using aggressive programming trim and/or multiple word line sensing for faster programming.

Example embodiments relate to a bad area managing method of a nonvolatile memory device. The nonvolatile memory device may include a plurality of memory blocks and each block may contain memory layers stacked on a substrate. According to example embodiments, a method includes accessing one of the memory blocks, judging whether the accessed memory block includes at least one memory layer containing a bad memory cell. If a bad memory cell is detected, the method may further include configuring the memory device to treat the at least one memory layer of the accessed memory block as a bad area.

A multi-chip package is provided. The multi-chip package includes a plurality of chips including at least one bad chip and at least one good chip that are stacked and a plurality of through electrodes each penetrating the chips. A logic circuit included in the at least one bad chip is isolated from each of the plurality of through electrodes.
摘要:
Testing systems and methods, as well as memory devices using such testing systems and methods, may facilitate testing of memory devices using a read-modify-write test procedure. One such testing system receives a signal indicative of at least some of a plurality of bits of data read from an address differing from each other, and then masks subsequent write operations at the same address. Therefore, any address at which the bits of read data do not all have the same value may be considered to be faulty. Failure data from the test can therefore be stored in the same array of memory cells that is being tested.
