Abstract: Methods, systems, and devices for techniques for managed NAND translation with embedded memory systems are described. A host system may generate a first command to access a logical memory address associated with a memory system. The host system may identify a physical memory address of the memory system based on generating the first command. The host system may output to the memory system a second command and the physical memory address, where the second command may be communicated to the memory device using a protocol associated with a controller of the memory system. The memory system may then access memory cells in a memory device associated with the physical memory address based on receiving the second command and the physical memory address.

Abstract: Various embodiments include methods, apparatus, and systems for assigning a plurality of version number values to instances of a logical entity of a memory device. Each version number value of the plurality version number values may be separately assigned to one of the instances of the logical entity. The version number values may be recycled after the plurality of version number values are assigned. Other embodiments including additional methods, apparatus, and systems are disclosed.

Abstract: Embodiments for partitioning a non-volatile memory device is described. In one embodiment a memory system includes a first addressable range of memory blocks for storing different types of data. The memory system is partitioned to include a second addressable range of memory blocks capable of storing data indicating attributes of the first addressable range of memory blocks. The second addressable range of memory blocks may also be periodically updated such that the capacities of the first addressable range of memory blocks may be dynamically adjusted depending on application needs and changes to the non-volatile memory device over time. In some embodiments, one partition of a memory device may be configured for high reliability data storage while a second partition is configured for normal reliability storage.

Abstract: Various embodiments include methods, apparatus, and systems for assigning a plurality of version number values to instances of a logical entity of a memory device. Each version number value of the plurality version number values may be separately assigned to one of the instances of the logical entity. The version number values may be recycled after the plurality of version number values are assigned. Other embodiments including additional methods, apparatus, and systems are disclosed.

Abstract: A single segment data structure and method for storing data objects employing a single segment data object having a header and a data record. The header includes a segment length field describing the length of memory reserved for the data record and the data record contains at least one data instance object. Each of the data instance objects has a data instance header and data field. The header includes a data instance state field and a data instance length field. The data instance length field contains data representing the length of the data instance data field allowing for variable length “in place” updating. The data instance state field contains data representing an object state of the instance data. Only one of the data instance objects of the data record of the single segment data object has a valid object state. The state field facilitates a power loss recovery process.
