Abstract
An electronic device includes a semiconductor memory that includes: a memory cell coupled between first and second lines and having a specific resistance state; a first read circuit suitable for supplying a predetermined pattern of a read voltage to the first line to generate a cell current corresponding to the specific resistance state of the memory cell during a read operation mode; and a second read circuit suitable for generating read data based on the cell current flowing through the second line during the read operation mode.
Claims20
An electronic device including a semiconductor memory, wherein the semiconductor memory comprises:
- a memory cell coupled between first and second lines, the memory cell having a specific resistance state;
- a first read circuit suitable for supplying a slow quenching pattern of a read voltage to the first line to generate a cell current, the cell current corresponding to the specific resistance state of the memory cell during a read operation mode;
- and
- a second read circuit suitable for generating read data based on the cell current flowing through the second line during the read operation mode.
A method of driving an electronic device including a semiconductor memory, the method comprising:
- supplying a predetermined voltage level of a read voltage to a first line coupled to a first end of a selected memory cell during an initial period of a read operation mode;
- supplying a slow quenching pattern of the read voltage to the first line during a subsequent period of the read operation mode, the subsequent period following the initial period;
- and
- generating read data based on a cell current flowing through a second line coupled to a second end of the selected memory cell during the subsequent period of the read operation mode.
