Method and system for programming multi-level cell memory

摘要

A method and a system for programming a multi-level cell (MLC) memory are provided. A first count is 1 initially. The method comprises the following steps. A first energy is set. The first energy is applied to alter a resistance of a cell of the MLC memory. The first count is increased by 1 after performing the step of applying the first energy. In the step of setting the first energy, the first energy is;a⁢⁢first⁢⁢initial⁢⁢energya⁢⁢predetermined⁢⁢value
