摘要:
Devices and techniques for variable width superblock addressing are described herein. A superblock width, specified in number of planes, is obtained. A superblock entry is created in a translation table of a NAND device. Here, the superblock entry may include a set of blocks, from the NAND device, that have the same block indexes across multiple die of the NAND device. The number of unique block indexes are equal to the number of planes and in different planes. A request, received from a requesting entity, is performed using the superblock entry. Performing the request includes providing a single instruction to multiple die of the NAND device and multiple data segments. Here, a data segment corresponds to a block in the set of blocks specified by a tuple of block index and die. A result of the request is then returned to the requesting entity.
