摘要:
A method is provided for programming a memory cell having a first terminal coupled to a word line and a second terminal coupled to a bit line. During a first predetermined time interval, the word line is switched from a first standby voltage to a first voltage, the bit line is switched from a second standby voltage to a predetermined voltage, and a voltage drop across the first and second terminals is a safe voltage that does not program the memory cell. During a second predetermined time interval, the word line is switched from the first voltage to a second voltage, and a voltage drop across the first and second terminals is a programming voltage that is sufficient to program the memory cell. Numerous other aspects are provided.
