Abstract:
1. A method of a host system transferring to a non-volatile memory system data of file objects through an interface adapted for connection with the non-volatile memory system, said non-volatile memory system being of a type having blocks of memory cells that are erasable together prior to being reprogrammed, comprising: maintaining at the interface a logical address space that is divided into logical blocks for storing addresses of data, designating addresses of data within individual ones of the file objects within one or more of the logical blocks, said one or more of the logical blocks storing addresses of data within the individual ones of the file objects, connect the non-volatile memory system to the host system through said interface wherein the non-volatile memory system is removable from the host system, provide a capability within the host system to receive through the interface, information about the data storage capacity of individual blocks of memory cells of the non-volatile memory system connected therewith, thereafter the host system receives said information from the non-volatile memory system, and in response to receiving said information through the interface, the host system being able to dynamically configure the sizes of the logical blocks of the logical address space to individually have the same data storage capacity as said information indicates to be possessed by the individual blocks of memory cells of the memory system.
