Abstract
A method and system for providing advance data type information to a mass storage system is disclosed. The method may include a host system providing host file information, such as a host file identifier and/or a data type, to a memory system in addition to LBA format data. The system may include a processor, a memory system interface and a host file system operative on the processor to identify and provide host file information and/or data type information to the memory system along with LBA format data.
Claims49
A method of transferring data between a host system and a re-programmable non-volatile mass storage system, the method comprising:
- identifying a data type of data to be transmitted next to the mass storage system;
- transmitting data type information to the mass storage system regarding the data type of the data to be transmitted next to the mass storage system, without providing identification of a particular host file to which the data type information pertains, wherein the data type comprises a first data type;
- and
- after transmitting the data type information, transmitting logical block address (LBA) information associated with the data to be transmitted next, and transmitting the data to be transmitted next, to the mass storage system.

A method of transferring data between a host system and a re-programmable non-volatile mass storage system, the method comprising:
- identifying a next data type of data to be transmitted next to the mass storage system;
- if the next data type differs from a previous data type of data last transmitted to the mass storage system, transmitting data type information to the mass storage information regarding the next data type prior to transmitting data having the next data type;
- and
- if the next data type is a same data type as the previous data type, transmitting the data having the next data type without transmitting data type information regardless of whether the data have the next data type and the data last transmitted are related to a common host file.
