Sorry to disagree, but that's not what I was told by the product engineers in Folsom. Maybe they bought
some and I don't remember the mix but most was made in house.

Just the Xeon full speed cache SRAM. Intel bought the chips for desktop Pentium IIs and IIIs.

"When Intel moved its CPUs from Socket 7 (Pentium) to Slot 1 (Pentium II) packaging, it began buying the
SRAM chips itself for integration onto the CPU modules. Previously, the SRAMs came on separate memory
boards, which PC manufacturers purchased and installed, along with the CPU and other components and
add-in cards, on the motherboard.

Only a few SRAM companies supply Pentium II L2 cache. Intel does not identify them, and nondisclosure
agreements prohibit the vendors from identifying themselves, but an often-repeated rumor indicates that
the companies are Mitsubishi, Motorola, NEC, Samsung, and Toshiba."
