RAM is not labeled in the '774 patent diagrams. Program ROM is clearly labeled in Figure 2 of the '774 patent which is another form of memory. However, the judge ruled that the device uses only flash memory, not RAM or any other memory system.

Accordingly, the Court concludes that the proper construction of the phrase “a flash memory module which operates as sole memory of the received processed sound electrical signals” is best addressed in two parts. The phrase “received processed sound electrical signals” refers to the electrical signals that have been generated by the microphone and passed through the amplifier and gain control circuits, but have yet to be converted by the CODEC. The remainder of the disputed language requires that the device use only flash memory, not RAM or any other memory system, while engaging the CODEC, DSP (as applicable), and memory control functions, as well as storing the fully-manipulated data.
