Integrated Silicon Solution Assigned Two Patents

Integrated Silicon Solution, (Cayman) Inc., Grand Cayman, Cayman Islands, has been assigned a patent (11626149) developed by Han, SungJin, San Jose, CA, for “SPI NOR memory with optimized read and program operation.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A serial NOR memory device receives serial input data using a single data rate (SDR) mode and transmits serial output data using a double data rate (DDR) mode. In some embodiments, a serial NOR memory device includes an input-output circuit including a transceiver coupled to receive a clock signal and serial input data and to provide serial output data. The transceiver is configured to receive serial input data using the single data rate mode and is configured to transmit serial output data using the double data rate mode.”

The patent application was filed on 2020-12-29 (17/137321).

Integrated Silicon Solution, (Cayman) Inc., Grand Cayman, Cayman Islands, has been assigned a patent (11621027) developed by Ong, Adrian E., Pleasanton, CA, for “MRAM architecture with multiplexed sense amplifiers and direct write through buffers.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A magnetic memory device for storing and quickly retrieving data from an array of magnetic memory elements. The array includes a plurality of magnetic memory element such as magnetic tunnel junction elements arranged in rows and columns. A plurality of multiplexed bit lines is connected with a first end of each of the magnetic memory elements and plurality of multiplexed source lines are connected with a second end of each of the magnetic memory elements. The multiplexing allows source line current and/or bit line current to be applied to an individual column of memory elements in the array for quick retrieval of data in a Magnetic Random Access Memory (MRAM) system.”

The patent application was filed on 2021-01-08 (17/145083).
