一、内存的类型 我们现在一般使用的微机常用内存有两种:DIP内存芯片和SIMM内存条。386SX以下档次微机主板上既有DIP内存芯片插座,又有SIMM内存插座,因此,既可以安装DIP内存芯片,又可以安装SIMM内存条;而386DX以上档次微机主板上只有SIMM内存插座,只能安装SIMM内存条。 DIP内存片是指普通双列直插内存芯片,常见单片容量有256KB、1MB等几种。SIMM内存条是指一小条焊接多片内存芯片的印刷电路板。内存条有统一的引线标准,按引线标准可划分为30线、72线和专用内存条3类。30线内存条常见容量有256KB、1MB和4MB;72线内存常见容量有4MB、8MB、16MB和32MB;专用内存条没有统一标准。常见于各种名牌机中。
First, the type of memory Us now commonly used microcomputer commonly used memory in two ways: DIP memory chips and SIMM memory. 386SX the following grades of computer motherboards both DIP memory chip socket, there are SIMM memory socket, so that both the DIP memory chips can be installed, but also can be installed SIMM memory; and above 386DX grade computer motherboard only SIMM memory socket, can only be installed SIMM memory module. DIP memory chip refers to the common dual in-line memory chips, common single-chip capacity of 256KB, 1MB and so on. The SIMM memory module is a small piece of printed circuit board that solves multiple memory chips. Memory has a unified lead standard, according to the standard lead can be divided into 30 lines, 72 lines and special memory 3 categories. Common memory capacity of 30-line memory is 256KB, 1MB and 4MB; common memory of 72-line memory is 4MB, 8MB, 16MB and 32MB; there is no uniform standard for memory. Common in a variety of brand name machine.
