A wireless system includes a TTI memory architecture in which encoded data are stored in a memory at a rate of one block of encoded data per transmission time interval (TTI), TTI being selected from a set of predetermined values, the memory including memory lines each having a predetermined number of bits that is determined according to the set of predetermined TTI values. For every block of data in which the end of the block of data does not align with an end of a last memory line occupied by the block of data, one or more padded bits are stored after the end of the block of data to the end of the last memory line occupied by the block of data so the last memory line is filled with a portion of the block of data and the one or more padded bits. The block of data and the padded bits are read in one or more equal sized segments.
