Cnex Labs Assigned Two Patents

Providing hybrid mode to access SSD drive
CNEX Labs, Inc., San Jose, CA, has been assigned a patent (10,331,364) developed by Huang, Yiren Ronnie, San Jose, CA, for “method and apparatus for providing hybrid mode to access SSD drive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A system configuration containing a host, solid state drive, (SSD), and controller able to perform a hybrid mode non-volatile memory, (NVM) access is disclosed. Upon receiving a command with a logical block address, (LBA) for accessing information stored in NVM, a secondary flash translation layer, (FTL) index table is loaded to a first cache and entries in a third cache is searched to determine validity associated with stored FTL table. When the entries in the third cache are invalid, the FTL index table in the second cache is searched to identify valid FTL table entries. If the second cache contains invalid FTL index table, a new FTL index table is loaded from NVM to the second cache. The process subsequently loads at least a portion of FTL table indexed by the FTL index table in the third cache.”

The patent application was filed on October 14, 2016 (15/294,547).

Computing system with shift data protection mechanism
CNEX Labs, Inc., San Jose, CA, has been assigned a patent (10,331,515) developed by Armstrong, Alan, Los Altos, CA, and Lee, Patrick, San Jose, CA, for a “computing system with shift data protection mechanism and method of operation thereof.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A computing system includes: a data block including data pages and each of the data pages includes data sectors and each of the data sectors include sector data and a sector redundancy, a storage engine, coupled to the data block, configured to: apply a first protection across the data pages includes shifted parities generated, apply a second protection across the data sectors, and correct at least one of the data sectors when a sector correction with the sector redundancy failed by selecting one of the shifted parities for the first protection and the second protection.”

The patent application was filed on December 10, 2015 (14/965,779).
