摘要:
A main memory system includes a main memory device including a first memory device implemented with a volatile memory and a second memory device implemented with a non-volatile memory, the main memory system being configured such that, when entering a sleep mode, the memory device reads a portion of data stored in the first memory device to store the read data in the second memory device, and, after the portion of data is read, the first memory device and the second memory device are powered off.

In one embodiment, the method includes receiving, at a storage device, a request. The request includes a request message authentication code and write protect information. The write protect information includes at least one of start address information and length information. The start address information indicates a logical block address at which a memory area in a non-volatile memory of the storage device starts, and the length information indicates a length of the memory area. The method also includes generating, at the storage device, a message authentication code based on (1) at least one of the start address information and the length information, and (2) a key stored at the storage device; authenticating, at the storage device, the request based on the generated message authentication code and the request message authentication code; and processing, at the storage device, the request based on a result of the authenticating.
摘要:
A method of booting an operating system can be provided by determining file information that is associated with files accessed during booting of an operating system by a processor. Files associated with the file information can be written into a non-volatile memory. The files can be transferred from the non-volatile memory to a volatile memory during a power on self-test of the processor.

A virtual device control method of a computing device which includes a nonvolatile memory is provided. The virtual device control method includes receiving a virtualization request; assigning a first part of the nonvolatile memory to a virtual memory; assigning a second part of the nonvolatile memory to a virtual storage; and generating a virtual device including the assigned virtual memory and virtual storage.

Disclosed are a soft handoff system, a soft handoff method, and a mobile terminal equipped with the soft handoff system. The soft handoff system for a mobile terminal analyzes periodically monitored wireless conditions of neighbor base stations, transmits a PSMM (Pilot Strength Measurement Message) to a current base station when a condition arises that needs reporting to the current base station, receives an HDM (Handoff Direction Message) from the current base station, wherein upon receiving the HDM from the current base station, the system allows a handoff drop timer of an active base station belonging to an active set having a pilot channel signal strength less than a predetermined value to continue running rather than to be reset until the handoff drop timer expires.
摘要:
A storage device includes a storage media including a one or more nonvolatile memories and a controller. The controller controls the nonvolatile memories, provides a virtual storage to an external host via at least one of the nonvolatile memories and erases a memory block of corresponding nonvolatile memory including data at physical addresses corresponding to data in the virtual storage.

A composition for removing a photoresist pattern includes about 5 percent by weight to about 20 percent by weight of an aminoethoxy ethanol, about 2 percent by weight to about 10 percent by weight of a polyalkylene oxide, about 10 percent by weight to about 30 percent by weight of a glycol ether compound, and a remainder of an aprotic polar solvent including a nitrogen. Thus, the photoresist pattern can be easily removed from a substrate, thereby improving the removing ability of the composition. In addition, a residual amount of the photoresist pattern may be minimized, thereby improving the reliability of removing the photoresist pattern.
摘要:
A main memory system is provided which includes a nonvolatile memory including a first memory area designated to store an operating system program and a second memory area designated to store user data; and a memory controller configured to control the nonvolatile memory such that the operating system program is loaded onto the second memory area from the first memory area. The nonvolatile memory may be one of a phase change RAM, a resistive RAM, and a magnetic RAM.
摘要:
A reactive mesogen compound, a liquid crystal composition including the reactive mesogen compound, a method of manufacturing a display panel, and a display panel are disclosed. The reactive mesogen compound may be activated by light having a wavelength between about 300 nm and about 700 nm.
摘要:
A memory cell includes a light emitting unit, a phosphorescent layer, a polarization filter and a light detecting unit. The light emitting unit selectively generates a first light signal in response to a write data. The phosphorescent layer generates a second light signal using an energy absorbed from the first light signal. The polarization filter either passes the second light signal to output the passed second light signal as a third light signal or blocks out the second light signal in response to the write data. The light detecting unit generates a read data by detecting the third light signal.
