100. Column latches, like other latches, typically are made up of electronic circuits called flip-flops. A flip-flop can, in turn, be constructed in a variety of ways, but each of those
ways involves some arrangement of transistors (which are simply electronic switches). Each flip-flop can store a single bit of data, and a series of flip-flops make up the column latches. The
'148 Patent teaches using column latches in several innovative ways, such as using a 1024-bit column latch as a long video shift register to drive a CRT display directly, and using two 1024- bit column latches to operate as the equivalent of two 32x32-bit register arrays (with the advantage of the column latch being about twice as fast as a register array). Regardless of how they are used, column latches, like registers and cache memory, have memory cells that are capable of maintaining their state for a period of time, and they include control circuitry, and therefore they are a type of memory.

101. I understand that TPL proposes that these phrases should be construed as "the total surface of the supporting material upon or within which is formed an interconnected array of circuit elements" and "the surface of the supporting material upon or within which is formed an interconnected array of circuit elements." I believe that these constructions are correct and
consistent with the understanding of a person of ordinary skill in the art.
