  • Patent number: 8223559
    Abstract: 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.

  • Patent number: 7965551
    Abstract: A method for metal bit line arrangement is applied to a virtual ground array memory having memory cell blocks. Each memory cell block has memory cells and m metal bit lines, wherein m is a positive integer. The method includes the following steps. First, one of the memory cells is selected as a target memory cell. When the target memory cell is being read, the metal bit line electrically connected to a drain of the target memory cell is a drain metal bit line, and the metal bit line electrically connected to a source is a source metal bit line. Next, a classification of whether the other metal bit lines are charged up when the target memory cell is being read is made. Thereafter, the m metal bit lines are arranged such that charged up metal bit lines are not adjacent to the source metal bit line.
