发明名称 Method of programming a memory
摘要 A method of programming a memory, wherein the memory includes many memory regions having multiple multi-level cells. Each memory region includes a first bit line, a second bit line, a data buffer and a protecting unit. The protecting unit, coupled to the first and second bit lines, and the data buffer, prevents a programming error from occurring. In an embodiment of the programming method, corresponding data are inputted to the data buffers respectively. The data corresponding to an nth phase are programmed into the targeted multi-level cells. Data corresponding to an (n+1)th phase is modified to make the data corresponding to the (n+1)th phase be the same as the data corresponding to the nth phase if the targeted multi-level cells pass a programming verification process according to an nth programming verification voltage. The above steps are repeated until n is equal to a maximum, n being a positive integer.
