Latest Patents

One of Yu-Hao Chang's latest patents is a data storage device and control method for non-volatile memory. This innovation provides a solution for deteriorated non-volatile memory. When the controller determines that raw data read from the non-volatile memory is undesirable, it updates a deterioration table to record the deteriorated logical address of the raw data. In response to a read request from a host, the controller retrieves the deteriorated logical address from the table and informs the host of the deterioration.

Another notable patent by Chang also focuses on a data storage device and control method for non-volatile memory. This invention addresses the safety moving of valid data from an erasure unit that contains undesirable raw data. The controller performs this safety moving to protect valid data in high-risk blocks, ensuring that the raw data is altered to differentiate it from the undesirable data. In exemplary cases, the undesirable data may consist of all-1's or all-0's data.
