Abstract: A memory device includes an array of composite memory units. At least one of the composite memory units comprises a first memory cell of a first type, a second memory cell of a second type, a first intra-unit data path connecting the first memory cell to the second memory cell, and a first data path control switch. The first data path control switch is responsive to a data transfer enable signal which enables data transfer between the first memory cell and the second memory cell through the first intra-unit data path.

Abstract: A flash memory device and a controlling method are provided. The flash memory device includes a memory array, an in-place update module, an out-of-place update module and a latency-aware module. The in-place update module is used for performing a program procedure or a garbage collection procedure via a bit erase operation or a page erase operation on the memory array. The out-of-place update module is used for performing the program procedure or the garbage collection procedure via a block erase operation or a migration operation on the memory array. The latency-aware module is used for determining a relationship between a first overhead of the in-place update module and a second overhead of the out-of-place update module.

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.

Abstract: A method for managing utilization of a memory including a physical address space comprises mapping logical addresses of data objects to locations within the physical address space, and defining a plurality of address segments in the space as an active window. The method comprises allowing writes of data objects having logical addresses mapped to locations within the plurality of address segments in the active window. The method comprises, upon detection of a request to write a data object having a logical address mapped to a location outside the active window, updating the mapping so that the logical address maps to a selected location within the active window, and then allowing the write to the selected location. The method comprises maintaining access data indicating utilization of the plurality of address segments in the active window, and adding and removing address segments from the active window in response to the access data.

Abstract: A method is provided for managing a memory device including a plurality of physical memory segments. A logical memory space is classified into a plurality of classifications based on usage specifications. The plurality of physical memory segments is allocated to corresponding logical addresses based on the plurality of classifications, and on usage statistics of the physical memory segments. A data structure is maintained recording translation between logical addresses in the logical memory space and physical addresses of the physical memory segments. The plurality of classifications includes a first classification and a second classification having different usage statistic requirements than the first classification. Logical addresses having the second classification can be redirected to physical segments allocated to logical addresses having the first classification, and the data structure can be updated to record redirected logical addresses. A free command can release a physical memory segment allocated for main memory use.

Abstract: A method is provided for managing a file system including data objects. The data objects, indirect pointers and source pointers are stored in containers that have addresses and include addressable units of a memory. The objects are mapped to addresses for corresponding containers. The indirect pointer in a particular container points to the address of a container in which the corresponding object is stored. The source pointer in the particular container points to the address of the container to which the object in the particular container is mapped. An object in a first container is moved to a second container. The source pointer in the first container is used to find a third container to which the object is mapped. The indirect pointer in the third container is updated to point to the second container. The source pointer in the second container is updated to point to the third container.
