International Classification:

G06F 3/06
G11C 16/04
G11C 11/56

Abstract:

Electronic systems might include a plurality of groups of memory cells and a controller for access of the plurality of groups of memory cells that is configured to cause the electronic system to determine whether a reliability of a particular group of memory cells having a particular reliability rank allocated for storing data of a particular data level at a particular memory density is less than a target reliability, and, if so, determine whether the reliability of the particular group of memory cells at a reduced memory density is less than the target reliability, and, in response to determining that the reliability of the particular group of memory cells at the reduced density is less than the target reliability, allocate the particular group of memory cells for storing data of a lower data level and allocate a different group of memory cells for storing data of the particular data level.

International Classification:

G06F 3/06
G06F 12/10
G11C 16/24
G11C 16/34

Abstract:

Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a criticality value can be determined and used as a basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a criticality value associated with performing a garbage collection operation satisfies a condition. Based on determining that the condition is satisfied, a parameter associated with performing the garbage collection operation can be adjusted. The garbage collection operation is performed on the data block stored on the memory component using the adjusted parameter.

G06F 13/16

Abstract:

Methods of operating a memory having a first pool of memory cells having a first storage density and a second pool of memory cells having a second storage density greater than the first storage density, as well as apparatus configured to perform similar methods, might include determining whether a value of an indication of available power is less than a threshold, and, in response to determining that the value of the indication of available power is less than the threshold, increasing a size of the first pool of memory cells, limiting write operations of the memory to the first pool of memory cells, and postponing movement of data from the first pool of memory cells to the second pool of memory cells.

International Classification:

G06F 12/10
G06F 13/16

Abstract:

Systems, apparatuses, and methods related to data compaction in memory or storage systems or sub-systems, such as solid state drives, are described. For example, one or more memory pages storing valid data can be identified from a first data block in a plane of a memory component and copied to a page buffer corresponding to the plane. A controller of the system or sub-system can determine whether the plane of the memory component has another data block with capacity to store the one or more memory pages and can copy the one or more memory pages from the page buffer either to the other data block or to a different data block in a different plane of the memory component.

G06F 12/02

Abstract:

Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a signaling can be received that indicates a request from a controller to migrate valid data from a first data block to a second data block. For example, the first data block can be a data block of a plurality of memory cells configured as single-level-cell (SLC) memory. The second data block can be configured as multi-level-cell (MLC) memory. The data migration operation can include an error control operation that is performed using the memory component, the error control operation excluding transferring the data to the controller. The data can be migrated from the first data block configured as SLC memory to the second data block configured as MLC memory after the error control operation is performed using the memory component.

Abstract:

Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a battery state associated with the memory system or sub-system may be used as an indicator or basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a battery state or condition satisfies a criterion. Based on determining that the criterion is satisfied the, the garbage collection operation may be postponed until the battery state changes to satisfy a different battery condition.

G06F 12/02

Abstract:

Systems and methods for read operations and management are disclosed. More specifically, this disclosure is directed to receiving a first read command directed to a first logical address and receiving, after the first read command, a second read command directed to a second logic address. The method also includes receiving, after the second read command, a third read command directed to a third logical address and determining that the first logical address and the third logical address correspond to a first physical address and a third physical address, respectively. The first physical address and the third physical address can be associated with a first word line of a memory component while the second logical address corresponds to a second physical address associated with a second word line of the memory component. The method includes executing the first read command and the third read command sequentially.
