For example, non-volatile memory devices are disclosed that utilize vertical structure NAND strings of serially-connected non-volatile memory cells. One such string including two or more serially-connected non-volatile memory cells where each end of the string shares a string select gate with the other end of the string is disclosed.
Architectures for data analytics using computational NAND memory
A data analytic system allows for analytic operations be moved from a server on to a solid state drive (SSD) type analytic system, where a CAM NAND structure can be used in the analytic operations. The server can run a software using database language can issue command to the analytic system. On the data analytic system (that can interface with common, existing database language), the software commands are translated into firmware language and broken down into multiple small tasks. The small tasks are executed on the SSD flash controllers or on NAND flash according to the task specifications. The mid-product from the NAND flash or the SSD controllers can be merged within each SSD blade and also further merged on the top server level.
Split data error correction code circuits
Split data error correction code (ECC) circuits including a control circuit coupled to an error correction code (ECC) circuit. The ECC circuit is adapted to generate at least one ECC code from user data of a first physical sector during a data access. The split data ECC circuit is adapted to write the at least one ECC code to a second physical sector if the data access is a write access and to compare the at least one generated ECC code with at least one ECC code stored in a second physical sector if the data access is a read access.
Resistance-change type non-volatile semiconductor memory
A memory cell is formed with a resistance variable element, which is interposed between first and second electrodes and can store resistance changes representing 2 or more different values, and first and second cell transistors having source terminals thereof connected to the first electrode, and gates thereof to a word line. A drain of the first cell transistor is connected to a bit line, and a drain of the second cell transistor is connected to a data line. The second electrode is connected to a source line. During a read operation, the first and second cell transistors are kept in an ON state, and a current is supplied from the bit line to the source line through the memory cell. Data is read according to the electrical potential difference between the data line and the source line.
Nonvolatile memory with bitline capacitive coupling compensation
A method of programming memory cells in a nonvolatile memory, includes applying a programming voltage to a first bitline and setting a second bitline in a floating state. The method further includes applying a compensation voltage to a shield conductive line coupled to the bitline set in the floating state, and setting in the floating state a shield conductive line coupled to the bitline receiving the programming voltage. The method is applicable to the reduction of the parasitic programming phenomena of memory cells by capacitive coupling between bitlines.
