Paragraph Number

64

"Erase block" refers to a logical erase block or a physical erase block. In one embodiment, a physical erase block represents the smallest storage unit within a given memory die that can be erased at a given time (e.g., due to the wiring of storage cells on the memory die). In one embodiment, logical erase blocks represent the smallest storage unit, or storage block, erasable by a storage controller in response to receiving an erase command. In such an embodiment, when the storage controller receives an erase command specifying a particular logical erase block, the storage controller may erase each physical erase block within the logical erase block simultaneously. It is noted that physical erase blocks within a given logical erase block may be considered as contiguous within a physical address space even though they reside in separate dies. Thus, the term "contiguous" may be applicable not only to data stored within the same physical medium, but also to data stored within separate media.
