Abstract
Methods and apparatus for NAND flash memory are disclosed. In an embodiment, a method is provided for programming a memory device having a plurality of memory chips that comprise multiple-level-cells. The method includes loading first data in a first chip, programming the first data into selected cells of the first chip using a single-level-cell (SLC) programming mode, and reprogramming the first data stored in the selected cells of the first chip to other cells of the first chip using a multiple-level-cell programming mode. The method also includes repeating the operations of loading, programming, and reprogramming for the remaining chips. The loading operations for the remaining chips begin at the completion of the loading operation for the first chip and occur in a non-overlapping sequential manner, and the loading operations for the remaining chips are performed in parallel with the programming and reprogramming operations of the first chip.
