View Edit Delete	US10998041B1	The physical erase blocks may be located in separate storage dies, shown as die 0 316, die 1 318, and die n 320. In certain embodiments, a die is divided into planes. "Plane" refers to a division of a die that permits certain storage operations to be performed on both planes using certain physical row addresses and certain physical column addresses.	104	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	"Storage block" refers to a set of storage cells organized such that storage operations can be performed on groups of storage cells in parallel. The organization of the set of storage cells may be implemented at a physical level or a logical level. Thus, a storage block, in one embodiment, may comprise a physical page, such as a word line, a logical page comprising physical pages that span planes and/or memory die, a physical erase block comprising a set of physical pages, a logical erase block (LEB) comprising a set of logical pages, or the like. A storage block may be referred to herein as a "block", a "memory block" or an LEB.	105	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	"Logical erase block" refers to another term for a storage block. In certain embodiments, a logical erase block refers to a set of logical pages that span planes, memory die, and/or chips. This organization of storage cells is deemed `logical` because the physical pages may not be directly coupled to each other. However, the physical pages are operated in parallel as though they are a single page. In like manner, multiple physical erase blocks may be operated in parallel as though they are a single erase block and are thus referred to as logical erase blocks. The terms logical erase block, metablock, and super block are used interchangeably herein.	106	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	"Logical page" refers to a collection of physical page that are treated as a single page for storage operations. "Physical page" refers to physical page represents the smallest storage block within a given memory die that can be written to in a single operation.	107	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	A logical erase block such as logical erase block 302 is further divided into multiple logical pages (logical page 322) that, in turn, includes multiple physical pages, such as physical page 0 324, physical page n 326, physical page 0 328, physical page n 330, physical page 0 332, and physical page n 334. Physical pages may include multiple packets, which may be grouped into error correction code (ECC) chunks.	108	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	In one embodiment, a physical page represents the smallest storage block within a given die that can be written to at a given time. In one embodiment, a logical page is the smallest writable storage block supported by the storage controller. (in one embodiment, the storage controller may include a buffer configured to store up to a logical page worth of data; upon filling the buffer, the storage controller may write the contents of the buffer to a single logical page simultaneously.) In some instances, dividing a logical page across multiple dies may result in faster access times for a set of data when multiple dies are accessed in parallel. The logical page configurations may be mapped to any physical page on a die, or across a plurality of memory dies, just as with logical erase blocks.	109	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	In some embodiments, a storage controller 102 may associate metadata, also referred to as media characteristics, with one or more of the storage blocks (logical erase blocks, physical erase blocks, logical pages, and/or physical pages). The storage controller 102 may manage metadata that identifies logical addresses for which a logical erase block stores data, as well as the respective numbers of stored data packets for each logical erase block, data block, or sector within a logical address space. A storage controller 102 may store metadata or media characteristic data in a variety of locations, including on non-volatile storage media, in volatile memory, in a structure stored with each logical erase block, or the like.	110	Added by DJM 12 2021	12/22/21, 12:00 AM
View Edit Delete	US10998041B1	"Media characteristic" refers to an attribute or statistic for a set of particular storage cells, such as a program/erase cycle count for the set of storage cells, a read count for the set of storage cells, a retention time since a previous write for the set of storage cells (aka a data retention time), a dwell time for the set of storage cells such as a logical or physical erase block (e.g., a time between a program of an erase block and an erase of the erase block), an average of multiple previous dwell times for the set of storage cells, an error statistic for the set of storage cells, or the like.	111	Added by DJM 12 2021	12/22/21, 12:00 AM
