Abstract

See full text

An example memory sub-system includes a memory device and a processing device, operatively coupled to the memory device. The processing device is configured to receive a read command specifying an identifier of a logical block and a page number; translate the identifier of the logical block into a physical address of a physical block stored on the memory device, wherein the physical address comprises an identifier of a memory device die; identify, based on block family metadata associated with the memory device, a block family associated with the physical block and the page number; determine a threshold voltage offset associated with the block family and the memory device die; compute a modified threshold voltage by applying the threshold voltage offset to a base read level voltage associated with the memory device die; and read, using the modified threshold voltage, data from a physical page identified by the page number within the physical block.
