He has made significant contributions to the field of memory devices, holding 3 patents that showcase his innovative approach to technology. His work primarily focuses on enhancing the functionality and reliability of NAND memory devices.

Latest Patents

One of his latest patents is titled "Page program not in order error detection." This invention modifies a NAND memory device to include current written page (CWP) and current written block (CWB) variables for each plane. When these variables are set, the NAND memory device performs an erase page check (EPC) on the indicated page and the previous page. The indicated page should be empty; otherwise, data will be overwritten when the page is written to. The previous page must be a programmed page; otherwise, the current page will skip the previous page during writing. The page write commands identify the page and block being written to, ensuring that the host system writes to the correct page.

Another significant patent by Liao is "Abnormal program sequence detection." This system and method detect abnormal program sequences on a memory device. A timing process is initiated by starting a timer or recording an initial timer value. The status register of the memory device is checked to determine if it is busy performing the program operation. The timer is stopped or a current timer value is recorded when the device is not busy. An elapsed time is determined to evaluate whether the program sequence was abnormal based on the checked operation time and defined operation time.
