Latest Patents
Huffman holds a patent for a "Sense circuit for multilevel storage system." This invention presents an improved sense circuit designed to determine the data state of a memory cell within a multilevel storage system. The circuit features at least two differential voltage level sensing circuits. The first circuit compares the magnitudes of a data input signal voltage level, which corresponds to a specific memory cell charge level, against a first reference voltage level. This comparison yields a first binary data output signal. This output is then utilized to generate a second reference voltage level, which differs from the first. The second differential voltage sensing circuit subsequently compares the adjusted data input signal voltage level with a second reference voltage level, producing a second binary data output signal. These binary data outputs reflect the charge level stored in the memory cell.
