Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. A memory device, comprising:
a memory array comprising a cell; and
a controller coupled to the memory array and configured to:
control sequentially applying programming voltage pulses to the cell, wherein:
a pulse width of each of a first subset of the programming voltage pulses keeps a same width, a pulse count of each of the first subset of the programming voltage pulses being less than a predetermined value, and
a pulse width of each of a second subset of the programming voltage pulses decreases as a pulse count of the second subset of the programming voltage pulses increases, a pulse count of each of the second subset of the programming voltage pulses being equal to or greater than the predetermined value.
