Abstract
Aspects of a storage device are provided that reduce calculations for identifying physical locations of data during a read operation. In one aspect, a memory device includes one or more memory arrays. Each array includes multiple chunks of memory. The device includes a first set of registers for storing prefixed starting addresses for each array. The device further includes control logic that may identify bad physical address in each array. For each successive chunk in each array and based on the prefixed starting address and the bad physical address locations, the device may determine a pointer to a starting physical address for the chunk. The pointer may be stored in a second set of registers for use in register read operations.
