The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method performed by a solid state drive is described. The method includes, on a channel that internally couples a controller of the solid state drive to a storage device of the solid state drive, sending write data for a program operation to be performed by one of the storage device’s logical units in separate chunks over the channel. The method also includes inserting higher priority traffic items of other logical units of the storage device in between the separate chunks.”

The patent application was filed on 2019-12-12 (16/712647).

Load reduced NVM interface
SK hynix NAND Product Solutions Corp., San Jose, CA, has been assigned a patent (11789880) developed by Chung, Emily P., Austin, TX, Hady, Frank T., and Vergis, George, Portland, OR, for a “load reduced nonvolatile memory interface.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage circuit includes a buffer coupled between the storage controller and the nonvolatile memory devices. The circuit includes one or more groups of nonvolatile memory (NVM) devices, a storage controller to control access to the NVM device, and the buffer. The buffer is coupled between the storage controller and the NVM devices. The buffer is to re-drive signals on a bus between the NVM devices and the storage controller, including synchronizing the signals to a clock signal for the signals. The circuit can include a data buffer, a command buffer, or both.”

The patent application was filed on 2022-10-21 (17/971201).

Automatic vent for SSD cooling enhancement
SK hynix NAND Product Solutions Corp., Rancho Cordova, CA, has been assigned a patent (11789506) developed by Sun, Yanbing, China, Liang, Xiaoguo, Gong, Haifeng, and Zhang, Ming, Shanghai, China, for an “automatic vent for SSD cooling enhancement.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Provided are devices and methods relating to temperature control in a solid state drive (SSD). One embodiment include a SSD including a housing including a plurality of sides surrounding an interior region. The SSD includes at least one vent on the housing, the at least one vent configured to be opened and closed in response to a signal. The SSD also includes a temperature sensor and a controller, the controller configured to send a signal to open the at least one vent when a temperature sensed inside the interior region reaches a first temperature, and the controller configured to close the at least one vent when a temperature sensed inside the interior region reaches a second temperature, wherein the first temperature is greater than the second temperature. Other embodiments are described and claimed.”

The patent application was filed on 2021-12-06 (17/543398).

NAND-based storage device with partitioned nonvolatile write buffer
SK hynix NAND Product Solutions Corp., San Jose, CA, has been assigned a patent (11709623) developed by Wysoczanski, Michal, Koszalin, Poland, Karkra, Kapil, Chandler, AZ, Wysocki, Piotr, Gdansk, Poland, and Ramalingam, Anand S., Portland, OR, for “NAND-based storage device with partitioned nonvolatile write buffer.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage system includes a NAND storage media and a nonvolatile storage media as a write buffer for the NAND storage media. The write buffer is partitioned, where the partitions are to buffer write data based on a classification of a received write request. Write requests are placed in the write buffer partition with other write requests of the same classification. The partitions have a size at least equal to the size of an erase unit of the NAND storage media. The write buffer flushes a partition once it has an amount of write data equal to the size of the erase unit.”

The patent application was filed on 2018-08-03 (16/054983).

Direct map memory extension for storage class memory
SK hynix NAND Product Solutions Corp., Rancho Cordova, CA, has been assigned a patent (11698859) developed by Barczak, Mariusz, Gdansk, Poland, for a “direct map memory extension for storage class memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An embodiment of an electronic apparatus may include one or more substrates, and logic coupled to the one or more substrates, the logic to receive a first request to allocate a direct swap file associated with an application stored in a system memory on a persistent storage media, and map a linear and continuous space of the persistent storage media to the direct swap file associated with the application in response to the first request. Other embodiments are disclosed and claimed.”

The patent application was filed on 2019-12-27 (16/728457).

SSD with external software execution to effect internal SSD operations
SK hynix NAND Product Solutions Corp., Rancho Cordova, CA, has been assigned a patent (11687471) developed by Tarango, Joseph D., Longmont, CO, Eike, Randal, Lyons, CO, Allison, Michael, Longmont, CO, and Hoffman, Eric, Lafayette, CO, for a “solid state drive with external software execution to effect internal solid-state drive operations.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method is described. The method includes executing solid state drive program code from system memory of a computing system to perform any/all of garbage collection, wear leveling and logical block address to physical block address translation routines for a solid state drive that is coupled to a computing system that the system memory is a component of.”
