Abstract:
An image forming apparatus supporting a near field communication (NFC) function and a method of performing setting an image job by using an NFC device. The method includes tagging an NFC device to receive setting information stored in the NFC device and performing an image job based on the received setting information.
Abstract:
In a method of writing data in a nonvolatile memory device, a write command, a write address and write data to be programmed are received. Offset information representing a verification level is received. The offset information is provided when the write data corresponds to a distribution deterioration pattern by checking an input/output (I/O) pattern of the write data. When the offset information is received, the write data is programmed based on the offset information such that at least one state among a plurality of states included in a distribution of threshold voltages of memory cells in which the write data is stored is changed.
Abstract:
Disclosed is an operation method of a controller which is configured to control a nonvolatile memory device. The method includes receiving cell counting data associated with selected memory cells included in the nonvolatile memory device from the nonvolatile memory device, adjusting operation parameters of the nonvolatile memory device based on the cell counting data, performing a valley search operation for the selected memory cells based on the adjusted operation parameters, and performing a read operation for the selected memory cells based on a result of the valley search operation.
