    Abstract: A memory system for maintaining data consistency and an operation method thereof are provided. The operation method includes: receiving a first data in a first cache of a first memory from a processor; reading the first data from the first cache and writing the first data as a redo log into a log buffer of the first memory; writing the redo log from the log buffer into a memory controller of the processor; performing an in-memory copy in a second memory to copy a second data as an undo log, wherein the second data is an old version of the first data; and writing the redo log from the memory controller into the second memory for covering the second data by the redo log as a third data, wherein the redo log, the third data and the first data are the same.

    Abstract: A data processing system comprises a storage device, an interface module and a scheduler. The interface module is configured to dispatch a non-prioritized request via a first data path, and to transfer application-level information of an application via a second data path. The scheduler, coupled to the first and second data path, is configured to enable an access to the storage device according to the non-prioritized request and the application-level information respectively received from the first and second data paths.

    Abstract: Technology is described that supports reduced program disturb of nonvolatile memory. A three/two dimensional NAND array includes a plurality of pages, which are divided into a plurality of page groups. Access is allowed to memory cells within a first page group of a plurality of page groups in an erase block of the three dimensional NAND array, while access is minimized to memory cells within a second page group of the plurality of page groups in the erase block of the three/two dimensional NAND array. Pages in the same page group are physically nonadjacent with each other in the three/two dimensional NAND array.

    Abstract: Disclosed is a management system for managing a memory device having sub-chips each having a container area and a data area. A CPU selects a target sub-chip according to respective temperature of the sub-chips. When the CPU intends to access a first original data in one of the data areas, a hot date tracking device acquires a first original address of the first original data from the CPU. When the first original address is recorded in one of a plurality of tracking layers, the CPU is indicated to access a first copied data corresponding to the first original data in the container area of the target sub-chip according to a current tracking layer recording the first original address. When the first original address is not recorded in the tracking layers, the CPU accesses the first original data in the data area according to the first original address.
