    摘要: A method of operating a cross-point memory device, having an array of multilevel cells, includes performing a first reading operation with respect to the multilevel cells through a plurality of sensing operations to determine a first state and performing a second reading operation with respect to the multilevel cells through a plurality of sensing operations to determine a second state. A difference between a level of a first voltage used in a first sensing operation and a level of a second voltage used in a second sensing operation in the first reading operation is different from a difference between a level of a third voltage used in a first sensing operation and a level of a fourth voltage used in a second sensing operation in the second reading operation.

    摘要: A method of operating a flash memory device includes a first operating mode and a second operating mode having different operating speeds. Each one of the first and second operating modes includes a bit line set-up interval and at least one additional interval. The flash memory is divided into first and second mats connected to respective first and second R/W circuits. During the bit line set-up interval of the second operating mode, the flash memory controls operation of both the first and second R/W circuits in a time division approach to stagger respective peak current intervals for the first and second mats.

    摘要: A flash memory and a program method of the flash memory include applying a pass voltage to word lines to boost a channel voltage, which is discharged to a ground voltage. A program voltage is applied to a selected word line and a local voltage is applied to at least one word line supplied with the pass voltage while the program voltage is being applied to the selected word line. The local voltage is lower than the pass voltage and equal to or higher than the ground voltage. The boosted channel voltage may be discharged before the program voltage is applied to the selected word line.

    摘要: An internal voltage of a semiconductor memory device is controlled, where the internal voltage is set according to a reference voltage. The reference voltage is controlled according to first control data to increase the internal voltage to be higher than a target voltage in a power-up operation, and second control data is read. The reference voltage is then controlled according to the second control data to decrease the internal voltage to the target voltage.
