The Symmetrical  
Array  
At the heart of the Atmel architecture is a symmetrical array of identical cells,  
see Figure 1. The array is continuous from one edge to the other, except for bus repeat-  
ers spaced every four cells, see Figure 2 on page 5. At the intersection of each repeater  
row and column there is a 32 x 4 RAM block accessible by adjacent buses. The RAM  
can be configured as either a single-ported or dual-ported RAM(1), with either synchro-  
nous or asynchronous operation.  
Note:  
1. The right-most column can only be used as single-port RAM.
