The Intel Pentium II Processor
The Pentium II is a sixth-generation x86 architecture microprocessor by Intel, introduced on May 7, 1997. It was based on a modifed version of the P6 core first used for the Pentium Pro, but with improved 16-bit performance and the addition of the MMX instructions which had already been introduced on the Pentium MMX.
 
Unlike previous Intel processors such as the Pentium and Pentium Pro, the Pentium II was packaged in a slot-based form-factor rather than a socket one. This larger package was a compromise allowing Intel to separate the secondary cache from the processor while still keeping it on a closely coupled bus. This separate cache was slower (running at half the processor speed) than that in the Pentium Pro, but solved the Pentium Pro's low yields allowing Intel to introduce the Pentium II at a mainstream price level.
 
A low-end version of the Pentium II - essentially a Pentium II with less (or no) level 2 cache - was marketed under the name "Celeron". The Pentium II Xeon was a high-end version intended for use on servers.
 
By early 1999, the Pentium III superseded the Pentium II.

Intel Pentium II 266 MHz MMC-2, 512 KB cache on module Back Side
While the MMC-1 module used a PCI interface to connect to the notebook motherboard the MMC-2 (Mobile Module Connector 2) uses an AGP/PCI interface.
The MMC-2 has 10 rows and 400 pins.
On the 266MHz version the L2 cache is not included on the processor die. You see 2 cache RAMs and a controller chip on the backside of the module. The 333MHz version CPU includes the L2 cache.

With the later versions of the 300 MHz Mobile Pentium II Intel moved the L2 cache from the module onto the processor die. The transistor count therefore increased by almost 20 million and the die size doubled.

To reduce costs and provide a more easy way for processor upgrades, the mobile modules were superseded by just the processors packed in small packages. The BGA (Ball Grid Array) was introduced for mobile CPUs and in low-cost notebooks these BGA processors were soldered directly on the mainboard. To make a notebook upgradeable, the BGA processors had to be mounted on adaptors to fit into standardized micro-sockets on notebook mainboards. This CPUs use a BGA package and is soldered on a small PCB with pins to fit into a standard notebook socket. The complete package is called Micro-PGA1 and has 615 pins (243 of them are not connected).
