Abstract: Systems, apparatuses, and methods provide for a memory controller to manage a tiered memory including a zoned namespace drive memory capacity tier. For example, a memory controller includes logic to translate a standard zoned namespace drive address associated with a user write to a tiered memory address write. The tiered memory address write is associated with the tiered memory including the persistent memory cache tier and the zoned namespace drive memory capacity tier. A plurality of tiered memory address writes are collected, where the plurality of tiered memory address writes include the tiered memory address write and other tiered memory address writes in the persistent memory cache tier. The collected plurality of tiered memory address writes are transferred from the persistent memory cache tier to the zoned namespace drive memory capacity tier, via an append-type zoned namespace drive write command.

Abstract: A method is described. The method includes constructing a bitmap having a first dimension organized into bins of logical block addresses (LBA bins) and a second dimension organized into bins of physical block addresses (PBA bins). Coordinates of the bitmap indicate whether respective physical blocks of non volatile memory within one or more SSDs that fall within a particular PBA bin are being mapped to by an LBA that falls within a particular one of the LBA bins. The method includes using the bitmap during a rebuild of an LBA bin of an LBA/PBA table to avoid reading meta data for physical blocks that are not mapped to by an LBA that falls within the LBA bin.
