Abstract: Systems and methods are disclosed for generating efficient reads for a system having non-volatile memory (“NVM”). A read command can be separated by a host processor of the system into two phases: a) transmitting a command to a storage processor of the system, where the command is associated with one or more logical addresses, and b) generating data transfer information. The host processor can generate the data transfer information while the storage processor is processing the command from the host processor. Once the data transfer information has been generated and data has been read from the NVM, the data can be transferred.

Abstract: Systems and methods are disclosed for configuring a non-volatile memory (“NVM”). In some embodiments, each block of the NVM can include a block table-of-contents (“TOC”), which can be encoded (e.g., run-length encoded) and dynamically-sized. Thus, as user data is being programmed to a block, the size of a block TOC can be concurrently recalculated and increased only if necessary. In some embodiments, the NVM interface can use a weave sequence stored in the context information and at least one weave sequence associated with each page of a block to determine whether to replay across the pages of the block after system boot-up.
