目前在工业和民用两大领域中,微型计算机的发展十分迅速,而 EPROM 器件对微机地起着重要的作用。EPROM 自从诞生十年以来,在制造工艺方面取得十分惊人的发展。现在生产的 EPROM 只用单一的5 V 电源,而最大存取时间为200ns,象8 K 字节的芯片(Intel2764—20)在市场上很方便地就能购买到。因此,EPROM 不仅仅在系统的调试阶段,而且在产品调试完毕的成员中,还需要装入大量的 EPROM 芯片来存贮信息。 Currently in the two major areas of industry and civilian use, the development of microcomputers is very rapid, and EPROM devices play an important role on the microcomputer. EPROM since the birth of ten years, made a very alarming development in the manufacturing process. The EPROM is now manufactured using only a single 5 V power supply, with a maximum access time of 200 ns, as 8 Kbyte chips (Intel 2764-20) are readily available on the market. Therefore, EPROM not only in the system debugging phase, but also in the finished product debugging members, but also need to load a large number of EPROM chip to store information.
