No. Twere invented by the US arm of the British firm (at the time) Inmos.
Thank a fellow named S. Sheffield Eaton. This is also where the
ubiquitous "nibble mode" was invented.
For DRAM ultra-trivia fanatics, which Japanese company bought the rights
to produce the very fast 64K, 256K, and 1Mbit DRAMS that Eaton et al
(Inmos) designed and prototyped?
NMB Semiconductor. Their ads brag about speed speed speed.
