Innogrit Technologies Assigned Two Patents

Command based on-die termination for high-speed NAND interface
Innogrit Technologies Co., Ltd., Shanghai, China, has been assigned a patent (11709789) developed by Zhao; Gang, Chandler, AZ, Jiang; Wei, Fremont, CA, Chen; Jie, Milpitas, CA, and Chen; Lin, Cupertino, CA, for a “command based on-die termination for high-speed NAND interface.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems, apparatus and methods are provided for multi-drop multi-load NAND interface topology where a number of NAND flash devices share a common data bus with a NAND controller. A method for controlling on-die termination in a non-volatile storage device may comprise receiving a chip enable signal on a chip enable signal line from a controller, receiving an on-die termination (ODT) command on a data bus from the controller while the chip enable signal is on, decoding the on-die termination command and applying termination resistor (RTT) settings in the ODT command to a selected non-volatile storage unit at the non-volatile storage device to enable ODT for the selected non-volatile storage unit.”

The patent application was filed on 2021-10-29 (17/514079).

Decoding error correcting codes with historical decoding information
Innogrit Technologies Co., Ltd., Shanghai, China, has been assigned a patent (11695434) developed by Fu, Bo, Cupertino, CA, Chen, Jie, Milpitas, CA, and Wu, Zining, Los Altos, CA, for “systems and methods for decoding error correcting codes with historical decoding information.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods are provided for decoding data read from non-volatile storage devices. A method may comprise receiving a chunk of data read from a physical location of a non-volatile storage device and searching a memory for soft information associated with the physical location using a unique identifier associated with the physical location. The soft information may be generated from one or more previous decoding processes on previous data from the physical location. The method may further comprise retrieving the soft information identified by the unique identifier associated with the physical location from the memory, decoding the chunk of data with the soft information indicating reliability of bits in the chunk of data and updating the soft information with decoding information generated during the decoding.”

The patent application was filed on 2021-09-30 (17/489901).
