Abstract
A memory device includes N rows of memory cells and N word lines coupled thereto, respectively. A method of reading data from the memory device includes: applying a first pre-pulse voltage to an nth word line while applying a second pre-pulse voltage to an adjacent word line adjacent to the nth word line, the second pre-pulse voltage exceeding the first pre-pulse voltage, and n being an integer ranging from 1 to N; grounding the nth word line while maintaining the second pre-pulse voltage on the adjacent word line; pulling a voltage on the nth word line towards a start read level; and prior to the voltage on the nth word line reaching the start read level, driving a voltage on the adjacent word line to the first pre-pulse voltage.
