Abstract
A method for programming a non-volatile memory in a programming operation is provided. The non-volatile memory has a number of cells and each of part of the cells store data having at least 2 bits at least corresponding to a first page and a second page. The method includes the following steps. At least one programming pulse is provided. At least one first program-verify pulse is provided. A program-fail-reference signal is enabled. At least one second program-verify pulse is provided after enabling the program-fail-reference signal.
Claims6
A method for programming a non-volatile memory in a programming operation, the non-volatile memory having a plurality of cells, each of part of the cells storing data having at least 2 bits at least corresponding to a first page and a second page, the method comprising:
- providing at least one programming pulse;
- providing at least one first program-verify pulse;
- enabling a program-fail-reference signal;
- and
- providing at least one second program-verify pulse after enabling the program-fail-reference signal.
