摘要： A memory controller controlling a nonvolatile memory device having a plurality of memory blocks as a data storage space includes an error detection and correction circuit and a reclaim control unit. The error detection and correction circuit receives data from a memory block and calculates a comparison result by comparing a bit error rate of the received data and a predetermined value. The reclaim control unit determines whether or not to perform a read reclaim operation depending on the comparison result and a read voltage used to read the data. The read reclaim operation copies the data to a memory block different from a memory block having stored the data.

摘要： Embodiments of the inventive concept improve performance, energy efficiency, and capacity of storage solutions, for example, by reducing the data movement between the CPU and the storage device and increasing the available capacity of the underlying storage devices via in-storage support for data compaction. Embodiments include a storage apparatus and method for autonomous in-storage space compaction initiated by a host-side command and according to metadata specified by a host. A space compact engine can function as an independent module or logic section within a storage device, which can migrate data within the storage device, thereby freeing up capacity and making preexisting data more compact. The space compact engine can cause self compact operations, self compact and trim operations, move and compact operations, and/or merge and compact operations. The space compact engine can notify the host of the completion of the operations.

摘要： Systems and methods may provide for identifying an object in a managed runtime environment and determining an age of the object at a software level of the managed runtime environment. Additionally, the object may be selectively allocated in one of a dynamic random access memory (DRAM) or a non-volatile random access memory (NVRAM) based at least in part on the age of the object. In one example, the data type of the object is also determined, wherein the object is selectively allocated further based on the data type.

摘要： In a memory system having non-volatile memory and volatile memory, write data are stored in a write-coalescing buffer in the volatile memory until the write data is written to non-volatile memory. First and second level address mapping tables are stored in the volatile memory and corresponding first and second level address mapping tables are stored in the non-volatile memory, and furthermore the second level address mapping table in the volatile memory contains entries corresponding to only a subset of the entries in the second level address mapping table in the non-volatile memory. The first address-mapping table in volatile memory includes entries storing pointers to entries in the second address-mapping table in volatile memory, entries storing pointers to locations in the write-coalescing buffer, and entries storing pointers to locations in the non-volatile memory that store data.

摘要： According to one embodiment, a memory system includes a nonvolatile memory, detection unit, management unit, selection unit, and garbage collection unit. The nonvolatile memory includes memory areas divided into units of execution of garbage collection. The detection unit detects a data amount of data written to a different memory area among the memory areas when the garbage collection is executed, for each of the memory areas. The management unit manages a threshold set for each of the memory areas. The selection unit selects, based on the data amount and the threshold for each of the memory areas, a memory area whose data amount is smaller than the threshold of the memory area. The garbage collection unit executes the garbage collection on the memory area selected by the selection unit.
