description Apparatus and methods for storing data in a block to provide improved accessibility of the stored data in two or more dimensions. The data is loaded into memory macros constituting a row of the block such that sequential values in the data are loaded into sequential memory macros. The data loaded in the row is circularly shifted a predetermined number of columns relative to the preceding row. The circularly shifted row of data is stored, and the process is repeated until a predetermined number of rows of data are stored. A two dimensional (2D) data block is thereby formed. Each memory macro is a predetermined number of bits wide and each column is one memory macro wide.
