Mayberry's job is to come up with options for building ever-smaller transistors and keeping the performance train rolling well into the future. The floating-body cell idea is designed to improve the density of the cache memory that chip designers place on a processor.

Cache memory is used to store frequently accessed data directly on the chip, where it can be accessed much faster than data stored in system memory or on a hard drive. But SRAM (static RAM) cells currently used to make cache memory are not as dense as Intel would like, with six transistors needed to build a cell and store one bit of information.
