The Heart of MIDs (Mobile Internet Devices)
At the heart of Mobile Internet Devices (MIDs) lie two pieces of silicon. The CPU is named Silverthorne. The single-chip chipset Poulsbo. The CPU and single-chip chipset combination is called Menlow.
MIDs will no doubt have other pieces of silicon on the printed-circuit board inside to do things like surf the Internet.
An optional component of Menlow is a parallel ATA solid-state drive, the Z-P140 PATA SSD.
