>what is the name of the thread where you discuss the "bucket brigade" >chip? I dont know... The buckets are capacitors. At each clock, the charge of the previous is transfered to the next. The biggest chips had 4096 buckets and were made by Philips and Matsushita. The first ones appeared in the early 70ies.
