Wolley Assigned Patent

Wolley Inc., San Jose, CA, has been assigned a patent (11,074,183) developed by Chang, Yu-Ming, Zhubei, Taiwan, Kuo, Tai-Chun, Taipei, Taiwan, and Shung, Chuen-Shen Bernard, San Jose, CA, for “apparatus and method of read leveling for storage class memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method and apparatus for read wearing control for storage class memory (SCM) are disclosed. The read data control apparatus, located between a host and the SCM subsystem, comprises a read data cache, an address cache and an SCM controller. The address cache stores pointers pointing to data stored in logging area(s) located in the SCM. For a read request, the read wearing control determines whether the read request is a read data cache hit, an address cache hit or neither (i.e., read data cache miss and address cache miss). For the read data cache hit, the requested data is returned from the read data cache. For the address cache hit, the requested data is returned from the logging area(s) and the read data becomes a candidate to be placed in the read data cache. For read data cache and address cache misses, the requested data is returned from SCM.”

The patent application was filed on December 28, 2019 (Appl. No.16/729,306).
