摘要： The present invention provides a dual reference cell sensing scheme for non-volatile memory. A high voltage reference cell and a low voltage reference cell are individually coupled to two sense amplifiers for providing two distinct reference voltages for comparison against the memory cell voltage. The output of the two sense amplifiers is further connected to a second stage sense amplifier to determine the status of the memory. The dual reference cell sensing scheme provides an increased sensing window which increases performance under low voltage application. The dual reference cell sensing scheme can be implemented by either voltage-based, current-based, or ground.

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.

摘要： A method for accessing memory is provided. The memory includes many multi-level cells each having at least a storage capable of storing 2n bits, n is a positive integer. The method for accessing memory includes the following steps: Firstly, threshold voltages of the storage are defined into 2n level respectively, wherein each of the 2n level corresponds to a storage status of n bits, and most significant bits of the storage statuses which level 0 to level 2n/2−1 correspond to are different from most significant bits of the storage statuses which level 2n/2 to level 2n−1 correspond to. Next, a target data is divided into n portions and the divided target data is written into n temporary memories respectively. Then, n bits of the target data are written into the multi-level cell. Each of the n bits data is collected from each of the n temporary memories.

摘要： A pre-code device includes firstly memory circuit, an address decoder, and an alternative logic circuit. The first memory circuit includes a number of memory blocks and at east a replacing block. The memory blocks are pointed by a number of respective physical addresses. The replacing block is pointed by a replacing address. The address decoder decodes an input address to provide a pre-code address. The alternative logic circuit looks up an address mapping table, which maps defect physical address among the physical addresses to the replacing address, to map the pre-code address to the replacing address when the pre-code address corresponds to the defect physical address. The alternative logic circuit correspondingly pre-codes the pre-code data to the replacing block.
