Industry preps new ‘cheap’ HBM4 memory spec with narrow interface, but it isn’t a GDDR killer — JEDEC’s new SPHBM4 spec weds HBM4 performance and lower costs to
Although cheaper than HBM4 or HBM4E, SPHBM4 still requires stacked HBM DRAM dies that are physically larger and therefore more expensive than commodity DRAM ICs, an interface base die, TSV processing, known-good-die flow…
