    Abstract: A non-volatile semiconductor memory device comprises a memory cell array including a plurality of memory cells arrayed capable of storing information of N bits (N≧2) in accordance with variations in threshold voltage. A parity data adder circuit adds parity data for error correction to every certain data bits to be stored in the memory cell array. A frame converter circuit uniformly divides frame data containing the data bits and the parity data into N pieces of subframe data. A programming circuit stores the subframe data divided into N pieces in respective N sub-pages formed corresponding to the information of N bits.

    Abstract: A non-volatile memory device has a memory array comprising a plurality of memory cells. The array can operate in either a multilevel cell or single level cell mode and each cell has a lower page and an upper page of data. The memory device has a data latch for storing flag data and a cache latch coupled to the data latch. A read method comprises initiating a lower page read of a memory cell and reading, from the data latch, flag data that indicates whether a lower page read operation is necessary.

    Abstract: A non-volatile memory can perform a first operation (such as a write, for example) on a designated group of one or more addressed pages using a first set of data stored in the corresponding set of data latches and also receive a request for a second operation (such as a read, for example) that also uses some of these corresponding data latches with a second set of data. During the first operation, when at least one latch of each set of the corresponding become available for the second operation, the memory whether there are a sufficient number of the corresponding set of data latches to perform the second operation during the first operation; if not, the second operation is delayed. The memory subsequently can perform the second operation during the first operation when a sufficient number of latches become available; and if, in response to determining whether there are a sufficient number of the corresponding set of data latches to perform the second operation it is determined that there are a sufficient number, performing the second operation during the first operation.

    Abstract: High endurance non-volatile memory devices (NVMD) are described. A high endurance NVMD includes an I/O interface, a NVM controller, a CPU along with a volatile memory subsystem and at least one non-volatile memory (NVM) module. The volatile memory cache subsystem is configured as a data cache subsystem. The at least one NVM module is configured as a data storage when the NVMD is adapted to a host computer system. The I/O interface is configured to receive incoming data from the host to the data cache subsystem and to send request data from the data cache subsystem to the host. The at least one NVM module may comprise at least first and second types of NVM. The first type comprises SLC flash memory while the second type MLC flash. The first type of NVM is configured as a buffer between the data cache subsystem and the second type of NVM.

    Abstract: A nonvolatile memory device implements a program routine followed by a program-verify routine when recording or modifying stored data. The nonvolatile memory device may include an array of memory cells for storing data, a sense node, and a gating circuit for selectively connecting a bitline of the array of memory cells to the sense node. The nonvolatile memory device may also include a page buffer coupled to the sense node. The page buffer may include a main latch for storing data to be written in the nonvolatile memory device, a cache latch for storing data supplied on an input line of the nonvolatile memory device to be transferred in the main latch through a source liner and a temporary static latch connected to the main latch through the source line and to the cache latch through an auxiliary switch and for transferring data between the main latch and the cache latch. The cache latch may be isolated from the source line during execution of the program routine and of the program-verify routine.
