摘要： This disclosure is related to systems and methods for selective metadata storage in a system having multiple memories. In one example, a device may include a control circuit configured to selectively store a metadata base map in a first memory or a second memory. The metadata base map may include information to determine a physical memory address from a logical block address. The control circuit may also be configured to store metadata updates separately from the metadata base map. The metadata updates may comprise changes to the metadata base map. The control circuit may also be configured to selectively store the metadata updates in the first memory or the second memory based on characteristics of the device.

摘要： This disclosure is related to systems and methods for a structured mapping system for a memory device, such as a solid state data storage device. In one example, a data storage device may include a multi-level address mapping system. The multi-level address mapping system may be implemented completely independent of a host computer and a host computer operating system. Also, the multi-level mapping system may be stored to allow each level, or subsets of each level, to be re-written independently of the other levels or the other subsets.

摘要： The present disclosure describes various techniques resolving block boundary issues and reconstructing logical blocks in a block access storage device when there are resulting mismatches between logical and physical block sizes or alignments, such that logical blocks span multiple physical block boundaries in irregular ways. In one example, a method comprises the following features: receiving logical block addresses that are associated with a sequence of logical blocks; and locating a first portion of a logical block within a first physical block that is stored in a block access storage device based upon a logical block address of the logical block, wherein the logical block is part of the sequence of logical blocks, and wherein at least two logical blocks within the sequence of logical blocks have different sizes.

摘要： A storage device, e.g., an SSD, is configured to enable spanning for a logical block between pages of the device. In one example, a device includes a data storage module to receive data to be stored, wherein the data comprises a plurality of logical blocks, and wherein a size of the plurality of logical blocks exceeds a size of a first page of the device, and a spanning determination module to determine whether to partition one of the plurality of logical blocks into a first partition and a second partition, wherein the data storage module is configured to partition the one of the plurality of logical blocks into the first partition and the second partition and to store the first partition in the first page and the second partition in a second, different page when the spanning determination module determines to partition the one of the plurality of logical blocks.
