ABSTRACT:
A memory system including a non-volatile flash memory and a method for simultaneously selecting a plurality of memory blocks are disclosed. The memory system is organized into multiple main blocks each having multiple smaller blocks, emulating a disk drive. Control lines activate a number of modes. In a first mode, high-order address lines select only one block, while in a second mode, user-specified multiple blocks are selected. Blocks are selected by loading registers with selection bits or by using some of the address lines directly as selection bits. Each bit specifies one of the blocks, and each bit is independent of the others. The memory system also includes a predecoder and a controller which controls the predecoder and the registers so as to select at least two blocks of memory cells. In a third mode, all of the blocks are selected, and in a fourth mode, all blocks are deselected. Selecting multiple blocks allows simultaneous erasing, writing, and reading of multiple bytes stored in the memory.
