Memory controller and method for accessing a plurality of non-volatile memory arrays

A method for accessing a number, K, of non-volatile memories, each of the non-volatile memories having a plurality of sectors, the method comprising:

• receiving a first command to access the plurality of non-volatile memories for a data transfer of a predetermined number, N, of sectors;
• determining whether N is an integer multiple of K;
• when N is not an integer multiple of K and N is greater than K, reorganizing the first command into a second and at least one additional command, wherein execution of the second command will result in the data transfer of an integer multiple of K first sectors of the predetermined number, N, of sectors to or from the plurality of non-volatile memories concurrently in parallel, and execution of the at least one additional command will result in the data transfer of remaining sectors not included in the first sectors;
• and
• executing the second command and the at least one additional command.

A memory control system for use in a system having a main memory and a set of non-volatile memories, wherein each non-volatile memory of the set of non-volatile memories comprises a plurality of sectors in locations having a sequential order, wherein there is a predetermined number, K, of non-volatile memories in the set of non-volatile memories having a predetermined order beginning with a first non-volatile memory and ending with a last non-volatile memory, comprising:

• memory means for receiving data from the main memory;
• memory controller means for receiving a first command to write the data to the set of non-volatile memories, wherein the first command indicates a total number of sectors, N, into which the data is to be written;
• identifying means for identifying, when N is greater than K, and N is not an integer multiple of K, a first grouping of the data that includes data corresponding to an integer multiple of K sectors, and identifying within the data a second grouping of remaining data that includes data not included in the first grouping of the data;
• reorganizing means for reorganizing the first command into a second command and at least one additional command, wherein the second command is to write the first grouping of data, and the at least one additional command is to write the second grouping of data;
• and
• writing means for executing the second command by writing the first grouping of data contemporaneously to sectors in each non-volatile memory of the set of non-volatile memories, and for executing the at least one additional command by writing the second grouping of data into the set of the non-volatile memories.
