Intergrated circuits
intergrated circuits
"LSI" refers to the practice of putting more components, more transistors, and more functions on a single chip. This reduces the number of packages required to do the job, and reduces the circuit-board area required for the device. The microprocessor in any household PC or laptop is an example of a large-scale- integrated circuit. And by the way, while we're on the subject, they're "integrated" circuits, not "intergrated".
integrated circuits were introduced in 1958
in America
The DDR ram memory is a class of memory intergrated circuits which is used in computers. DDR has been superseded by DDR2 and DDR3 neither of which is either forward or backward compatible.
