Latest Patents
One of his latest patents is titled "Sense circuit for multilevel storage system." This invention presents an improved sense circuit designed to determine the data state of a memory cell in 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 and a reference voltage level, generating a binary data output signal. This output is then utilized to create a second reference voltage level, which is compared by a second differential voltage sensing circuit to produce additional binary data output signals. These signals correspond to the charge level stored in the memory cell.
Another significant patent by Rock is the "Memory input signal buffer circuit." This dynamic logic buffer circuit provides FET level complementary output signals in response to low-level input signals. It is compatible with various bipolar transistor driving logic families, allowing for external sensitivity adjustments. The circuit includes a cross-coupled dynamic latch that responds to gated input and reference signals, with voltage boosting capacitors enhancing the output nodes connected to dynamic output driver circuits.
