Filed: 2021-06-24
Abstract: The present disclosure generally relates to improving programming to a data storage device such as a solid state drive (SSD). A first memory device has a first XOR element, and a second memory device has a second XOR element. A ratio of the first XOR element to a capacity of the first memory device is substantially smaller than a ratio of the second XOR element to a capacity of the second memory device. A read verify operation looking for a program failure is performed on a word line to word line basis, on an erase block to erase block basis, or both the word line to word line basis and the erase block to erase block basis. Since the program failure is found and corrected before programming is performed on the second memory device, the second XOR element can be substantially reduced.
