随着计算机和集成电路的发展,基于半导体集成工艺的集成磁学——磁泡技术也应运而生。磁泡技术的问世给古老的磁学带来了新的生气,赋予新的内容,无怪乎国外一些人把磁泡技术的出现看做“挽救了磁学的危机”。十年来,磁泡理论、材料、工艺、器件和应用,突飞猛进,日新月异。与存贮密度密切相关的泡径大小已从早期的100微米降到现在的0.4微米,芯片容量已从1971年的1024位样件发展到现在的10~6位/片,八年间容量增大1000倍。1977年德克萨斯仪器公司(TI)92K位芯片(现月产5000片)上市后,充分显示了磁泡的优点,加速了磁泡的发展,采用磁泡存贮器的计算机、微处理
With the development of computers and integrated circuits, integrated magnetism-bubble technology based on semiconductor integrated technology has emerged. The advent of bubble technology has brought new life to the old magnetism and given new content. It is no surprise that some people abroad consider the emergence of bubble technology as “a crisis that has saved magnetism.” Over the past decade, bubble theory, materials, processes, devices and applications, by leaps and bounds, with each passing day. The bubble diameter, which is closely related to the storage density, has dropped from 100 micrometers in the early stage to 0.4 micrometers in the present. The chip capacity has increased from 1,024 bits in 1971 to the present 10 to 6 bits per piece, and the capacity has increased in eight years 1000 times. The 1977 Texas Instruments Incorporated (TI) 92K chip (now available in 5000 pieces) went on the market and fully demonstrated the benefits of a bubble, accelerated the development of bubble, a computer with a bubble memory, a microprocessor
