Abstract:
PURPOSE: A method for programming a nonvolatile memory device is provided to detect an instantaneous power cutoff by reading a monitoring cell with a monitoring voltage of a preset voltage level when a data cell is programmed. CONSTITUTION: A nonvolatile memory device including a data cell and a monitoring cell is provided(S100). The data cell stores N bit data. The monitoring cell monitors whether the data cell is programmed with the N bit data. The data cell is firstly programmed when the monitoring cell is inhibited(S110). The monitoring cell is secondly programmed when the data cell is inhibited.
Abstract:
PURPOSE: An operating method of a memory controller and a memory system including the memory controller are provided to reduce the maximum number of times of read retry operation for a storage area by calculating a time difference between a read operation and a program operation for the storage area of a nonvolatile memory. CONSTITUTION: An RTC(Real Time Clock) circuit(30-2) generates first and second RTC values in response to a clock signal. A microprocessor(30-1) controls a program for a nonvolatile memory of the first RTC value indicating a first view point. When read operation is performed, the microprocessor calculates a difference by using the first RTC value read from the nonvolatile memory and the second RTC value indicating a second view point. When read retry operation is performed, the microprocessor controls the reduction of the maximum number of times of the read retry operation by using the difference.

PURPOSE: A flash memory system and a lead method of the flash memory system are provided to quickly and accurately correct a lead error, thereby reducing the overhead of the system. CONSTITUTION: In a wear-out table which consider each of the block of flash memory as an index, the selection index of the selection block is updated (S120). When the current request of the lead retry of the selection block is received, with reference to the lead retry table which corresponds to the wear-out included in the selection index, the lead level starting the lead retry of the selection block is determined (S140). [Reference numerals] (S120) Update the indexes for selected blocks in a wear-out degree table in which each block of a flash memory serves as an index; (S140) Set a reading level at which a reading re-try is initiated for a selected block based on a reading re-try table corresponding to a wear-out degree included in a selected index when a request for a reading re-try for the selected block is received
Abstract:
The present invention relates to a method and a device for controlling a call in an electronic device. At this time, the method for controlling a call in a first electronic device can include an operation which receives a call connection request from a second electronic device through a base station; an operation which checks the generation of a call conversion event with regard to a call connection request received from the second electronic device; and an operation which requires a call connection request received from the second electronic device is converted to a third electronic device when the call conversion event is generated.
Abstract:
PURPOSE: A method and apparatus for reading data in a nonvolatile memory device are provided to improve the reliability of an error correction operation by reducing the time of a read retry operation. CONSTITUTION: An error is corrected by receiving data read in a target page of a nonvolatile memory device(S11). If the error correction operation is failed, a read voltage level is reset when an R/B signal is in a preparation mode(S14). A random cache read command for the target page is outputted to the nonvolatile memory device(S15). The error is corrected by receiving data which is temporarily stored in a second register from the nonvolatile memory device(S16). If the error correction operation is completed, the nonvolatile memory device is reset and a read operation is finished(S21).
Abstract:
PURPOSE: A method for circulating coolant of a stepper for fabricating a semiconductor is provided to maximize operating efficiency of the stepper, by sharing coolant circulated in an adjacent stepper even if an accident happens in a member for circulating coolant. CONSTITUTION: The coolant which maintains a temperature state set up in each stepper(20a,20b) for performing an exposure process, is circulated to maintain the temperature of the members at a predetermined state such that the members constitute the stepper when the exposure process is performed. When an accident happens in circulating the coolant, coolant circulated in a stepper adjacent to the stepper wherein the accident happens is shared to continuously maintain the temperature of the members constituting the abnormal stepper.
