MMC-1
Encyclopedia
Mobile Module Connector 1 (MMC-1), is a 280-pin microprocessor cartridge developed by Intel for used by their mobile Pentium, Pentium MMX, Pentium II
and Celeron
processors. It contains the microprocessor
and its associated L2 cache
, a 430TX for the Pentium or a 443BX for the Pentium II northbridge
, and a voltage regulator.
MMC-1 was more of a mechanical standard than an electrical one, since the southbridge of the 430TX chipset would not work correctly with the northbridge of the 443BX and vice versa. This was irrelevant for MMC-2
since the northbridge was always the 443BX.
Pentium II
The Pentium II brand refers to Intel's sixth-generation microarchitecture and x86-compatible microprocessors introduced on May 7, 1997. Containing 7.5 million transistors, the Pentium II featured an improved version of the first P6-generation core of the Pentium Pro, which contained 5.5 million...

Microprocessor
A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

CPU cache
A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations...

Northbridge (computing)
The northbridge has historically been one of the two chips in the core logic chipset on a PC motherboard, the other being the southbridge. Increasingly these functions have migrated to the CPU chip itself, beginning with memory and graphics controllers. For Intel Sandy Bridge and AMD Fusion...

MMC-2
Mobile Module Connector 2, Intel's 400 pin processor cartridge used with Pentium II, Celeron and Pentium III mobile processors. It contains CPU, 443BX Northbridge, L2 Cache and voltage regulator. It is successor of MMC-1, main differences being AGP interface and 100 MHz FSB for the Pentium...
