Mobile Module Connector
A Mobile Module Connector ( MMC ) is a socket developed by Intel for processor modules in notebooks .
MMC-1
Initially, a first generation of processor modules with sockets according to the MMC-1 specification was offered. It was used with the Mobile Pentium, Mobile Pentium MMX and Mobile Pentium II processors . The socket had four rows with a total of 280 pins. In addition to the processor, the processor module also contained the appropriate northbridge , level 2 cache and CPU voltage regulator . There was a PCI interface to the main board of the computer via the MMC-1 socket .
MMC-2
A second generation based on the MMC-2 specification was introduced later. The socket had 10 rows with a total of 400 pins. In addition to the processor, there was also a northbridge and CPU voltage regulator on the module. The cache was only on the module in early copies until processors with an integrated cache (on-die cache) came onto the market. There was an AGP / PCI interface to the main board , which already enabled fast 3D graphics.
