20130077382 | HYBRID MEMORY DEVICE, SYSTEM INCLUDING THE SAME, AND METHOD OF READING AND WRITING DATA IN THE HYBRID MEMORY DEVICE - A hybrid memory device is provided. The hybrid memory device includes a DRAM, a non-volatile memory and a control circuit. The control circuit selects one of output data of the DRAM and output data of the non-volatile memory according to a mode selecting signal and output the selected data. The control circuit outputs data requested to be output from the DRAM when the data requested to be output is in the DRAM, and may output the data requested to be output from the non-volatile memory when the data requested to be output is in the non-volatile memory. Accordingly, the hybrid memory device has a high speed in a read and write operation, and has low power consumption. | 03-28-2013 |
20130080693 | HYBRID MEMORY DEVICE, COMPUTER SYSTEM INCLUDING THE SAME, AND METHOD OF READING AND WRITING DATA IN THE HYBRID MEMORY DEVICE - A hybrid memory device includes a DRAM and a non-volatile memory. When a program is executed for the first time by a central processing unit (CPU), and data is copied to the DRAM from an external memory device, the data is also copied to the non-volatile memory. The non-volatile memory is configured to directly output data stored therein to an exterior without passing through the DRAM. | 03-28-2013 |
20140013066 | MEMORY SUB-SYSTEM AND COMPUTING SYSTEM INCLUDING THE SAME - A memory sub-system includes a main memory, a storage device, a control unit, and a common interface unit. The control unit is configured to control the main memory and the storage device. The common interface unit is operatively coupled to the control unit, and is configured to access the main memory and the storage device through the control unit in response to a request received from a host. | 01-09-2014 |
20140016397 | NONVOLATILE MEMORY DEVICE AND WRITE METHOD THEREOF - A nonvolatile memory device includes a memory cell array including a plurality of memory cells, and a data comparison write unit connected with the memory cell array and configured to support a comparison write operation. The nonvolatile memory device further includes control logic configured to selectively execute the comparison write operation based on a comparison between an access number of the memory cell array and a reference number. | 01-16-2014 |
20140032890 | STORAGE DEVICE COMPRISING VARIABLE RESISTANCE MEMORY AND RELATED METHOD OF OPERATION - A storage device includes a nonvolatile memory device including a variable resistance memory, and a controller configured to control the nonvolatile memory device. At a booting operation, the controller stores booting information in the variable resistance memory of the nonvolatile memory device. At a rebooting operation, the controller selectively performs a warm boot operation using the booting information stored in the variable resistance memory, based on a comparison result between a booting setting condition associated with the booting operation and a rebooting condition associated with the rebooting operation. | 01-30-2014 |
20140043892 | SEMICONDUCTOR MEMORY DEVICE HAVING VARIABLE RESISTANCE MEMORY AND OPERATING METHOD - A semiconductor memory device includes a memory cell array of nonvolatile memory cells having a variable resistance element, and a conductor line array capable of generating a compensation magnetic field for the nonvolatile memory cells. A current driver selectively supplies current to conductive lines, a magnetic field sensor senses an applied external magnetic field and generates external magnetic field information, and a controller controls generation of the compensation magnetic field in response to the external magnetic field information. | 02-13-2014 |
20140189183 | MEMORY SYSTEM AND DRIVING METHOD THEREOF - A memory system includes first and second memory devices, a memory controller configured to control the second memory device, to store a request signal to access the first memory device, and to generate an interrupt signal, and a host configured to receive the request signal in response to the interrupt signal. | 07-03-2014 |
20150039814 | STORAGE DEVICE AND STORAGE SYSTEM INCLUDING THE SAME - A storage device may include a nonvolatile storage and a storage controller. The nonvolatile storage may include a map table which stores information including a logical address, a physical address corresponding to the logical address and a correlation index designating the physical address. The storage controller is configured to transmit the information to an external host device, and to access the nonvolatile storage based on a request and the correlation index, each of the request and the correlation index transmitted from the host device. | 02-05-2015 |
