Wolly Inc., San Jose, CA, has been assigned a patent (11,016,686) developed by Chang, Yu-Ming, Zhubei, Taiwan, and Shung, Chuen-Shen Bernard, San Jose, CA, for “apparatus and method of bad location management for storage class memory using distributed pointers.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method and apparatus of bad location management for storage class memory are disclosed. A nonvolatile memory is partitioned into a non-reserved space and a reserved space, which are divided into multiple data units. The health status of the data units in the non-reserved space are classified into multiple classes including a mostly-good class. For host data read, the data from a mostly-good data unit are read and whether the data includes a pointer is checked. If no pointer, the data read are returned as the host data. Otherwise, the data unit pointed by the pointer is read. For data write, the data from a mostly-good data unit are read. If no pointer in the read data, the host data are written into the mostly-good data unit. Otherwise, the host data are written into the data unit in the reserved space pointed by the pointer.”

The patent application was filed on September 18, 2019 (Appl. No.16/574,104).
