PROBLEM TO BE SOLVED: To provide a semiconductor memory having high security and a computer system equipped with the semiconductor memory.SOLUTION: Host equipment 2 includes: a conversion part 12 for converting a command D1 to be transmitted to a semiconductor memory 3 by a predetermined ...
Semiconductor memories and methods of manufacturing such memories A semiconductor memory having storage cells each comprising a MIS transistor (6, 7, 13) and a capacitor (1, 2, 10) comprises a semiconductor substrate (1), an insulating layer (3) formed on the semiconductor substrate (1), and...
Britannica Quiz Computers and Technology Quiz Semiconductor memory There are two basic kinds of semiconductor memory. Static RAM (SRAM) consists of flip-flops, a bistable circuit composed of four to six transistors. Once a flip-flop stores a bit, it keeps that value until the opposite value ...
Computers small and inexpensive enough to be purchased by individuals for use in their homes first becamefeasiblein the 1970s, when large-scaleintegrationmade it possible to construct a sufficiently powerfulmicroprocessoron a singlesemiconductorchip. A small firm named MITS made the first personal comp...
A semiconductor integrated circuit has a plurality of ram (10, 11, 12), a replacement - ram (13) as well as test / repair - control logic (2, 3) which, under the plurality of ram a faulty ram is detected, on. When a faulty ram is detected, replacing selectors (20 - 22, 30 -...
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tiny MOSFETs (metal–oxide–semiconductor field-effect ...
last decade, advances in computer design and memory technology have greatly reduced the importance of small memory size in most applications other than those in embedded computing systems.Programmers interested in performance now need to understand the issues that have replaced the simple memory model ...
SRAM is a type of semiconductor memory and it uses bistable latching circuitry to store each bit, this makes it very fast and thus the name cache memory. However, it is much more expensive than DRAM (we’ll talk about it later) and takes up a lot more space so there’s lesser memory...
(metal–oxide–semiconductor field-effect transistors) integrate into a small chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block ...
thinking, and the computer on a chip was made possible. The air was electric with the possibility. 429 • Once the feat had been established, the rest of the decade saw a proliferation of companies old and new getting into the semiconductor ...
