Tillamook
Pentium MMX notebook CPUs used a mobile module that held the CPU. This module was a printed circuit board (PCB) with the CPU directly attached to it in a smaller form factor. The module snapped to the notebook motherboard, and typically a heat spreader was installed and made contact with the module. However, with the 250 nm Tillamook Mobile Pentium MMX (named after a city in Oregon), the module also held the 430TX chipset along with the system's 512 KB static random-access memory (SRAM) cache memory.
