As far as I'm aware, IBM is one of the few chip-designers who have eDRAM capabilities.
IBM has eDRAM on a number of chips in varying capacities, but... its difficult for me to think of Intel, AMD, Apple, ARM, or other chips that have eDRAM of any kind.
Intel had one: the eDRAM "Crystalwell" chip, but that is seemingly a one-off and never attempted again. Even then, this was a 2nd die that was "glued" onto the main chip, and not like IBM's truly eDRAM (embedded into the same process).
You're right. My bad. It's much less common than I'd thought.
(Intel had it on a number of chips that included the Iron Pro Graphics across Haswell, Broadwell, Skylake etc)
Crystalwell was the codename for the eDRAM that was grafted onto Broadwell. (EDIT: Apparently Haswell, but... yeah. Crystalwell + Haswell for eDRAM goodness)
