磁泡研究至今已有十余年,在理论、材料、工艺、器件、应用等方面都已取得了飞速的发展。磁泡存储芯片容量和密度每年增加一倍,工作频率不断提高,成本不断下降。美国西部若干半导体公司及厂家已经或正在筹划生产磁泡。据了解,日本日立制作所1978年月产64K芯片2000片,全年预计24000片,合1.5×10~9位,整个日本年产量估计5×10~9位。德克萨斯仪器公司预计1979年美国磁泡存储器销售额可达一亿美元(2×10~(11)位,每位0.05美分)。表1、2、3示出了几种磁泡存储器商品的特性;TBM 0103磁泡存储器模件商品价格200美元,为德克萨斯仪器公司所生产。此外,该公司还出售765型手提式存储终端,其中磁泡存储器容量20000字节,有键盘及能代替盒式磁带、纸带以及软盘功能的存储容量。有终端打印机,此外该终端还具有自检及编校能力。该存储终端的价格为2995美元。还有763型存储收发终端,功能较全,使用方便,价格2695美元。
Bubble bubble research has been more than ten years, has made rapid development in theory, materials, technology, devices, applications and so on. Bubble memory chip capacity and density doubled each year, working frequency continues to increase, the cost continues to decline. A number of semiconductor companies and manufacturers in the western United States have or are planning to produce bubble. It is understood that Japan’s Hitachi Ltd. in 1978 produced 64K chips 2000, the annual estimate of 24000, together 1.5 × 10 ~ 9, the entire Japanese annual production is estimated 5 × 10 ~ 9. Texas Instruments expects US bubble memory sales in 1979 to reach 100 million U.S. dollars (2 × 10-11) at 0.05 cents each. Tables 1, 2 and 3 show the characteristics of several bubble memory products; the TBM 0103 bubble memory module is priced at $ 200 and is manufactured by Texas Instruments. In addition, the company sells Model 765 portable storage devices, which contain 20,000 megabytes of bubble memory, a keyboard and storage capacity that can replace tape cassettes, tapes and floppy disks. A terminal printer, in addition to the terminal also has self-test and editing ability. The storage terminal costs $ 2995. There are 763 storage terminal transceiver, full-featured, easy to use, the price of 2695 US dollars.
