目前,在计算机系统特别是微型机系统中半导体存贮器芯片应用得非常广泛,但当国外研究出了磁泡存贮器后,许多人开始怀疑半导体存贮器芯片将来会不会被淘汰。磁泡存贮器是贝尔实验室研究出来的,目前多用正铁氧体、石榴石型铁氧体等材料制造。这些单晶强磁性薄膜或多晶台金磁膜在外加磁场作用下产生许多磁泡。磁泡在电路的控制下按规定方式移动形成存贮器件,其存贮密度可达1.6×10~5位/平方毫米。1979年,得克萨斯仪器公司、富士通、英特尔、洛克韦尔等公司就开始使用了磁泡存贮器,因这种存贮器很有前途,所以有许
At present, semiconductor memory chips are widely used in computer systems, especially in micro-computer systems. However, when foreign countries have developed bubble memories, many people begin to wonder whether the semiconductor memory chips will be eliminated in the future. Bubble memory is Bell Labs out of research, the current use of regular ferrite, garnet ferrite and other materials. These single crystal ferromagnetic films or polycrystalline gold magnetic films produce a large number of magnetic bubbles under the action of an external magnetic field. Bubble in the circuit under the control of the mobile form the formation of storage devices, the storage density of up to 1.6 × 10 ~ 5 / mm2. In 1979, Texas Instruments, Fujitsu, Intel, Rockwell and other companies began to use the bubble memory, because this memory is very promising, so there is promise
