i7-5775C: why did Intel abandon development of eDRAM?

The site is oem xs at ebay stores. Remember those intel pentium 840 extreme edition CPU's; I bought a bunch of them and flipped them back in 2008. It was a real good lick until someone told on me and the price quadrupled overnight LOL! It looks like she has expanded into a lot of other merch since then, Enjoy.

From what I understand Intel's i7-5775C wasn't produced in large numbers yet had performance above and beyond 4-core/8-thread CPU's of the day, so why did Intel abandon development of eDRAM for CPU's? 128MB of eDRAM proved its worth w/the i7-5775C.

That's because in this day and age, you don't have to reinvent the wheel with existing technologies that already exist. Intel does use a form of DRAM on Sapphire Rapids for certains SKUs. They have 64GB of HBM2e on package for these products.
