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).
