本文介绍一种电流重合法磁心存储器,其容量为16384字,每字为27位。周期时间为1.2微秒,标称开关时间≤0.6微秒。采用外径为30密耳厚的环状铁氧体磁心,磁心的温度系数较低,允许工作环境温度高达75℃,并且不需要采用通风设备。这种存储器的驱动与读出系统的结构非常简单,用简便的方法就可消除变压器矩阵内的容性干扰电流。选择系统和禁止驱动器均采用悬空输出的驱动方式。读出放大器的直流恢复用控制其增益的办法来实现,这样,不会降低其工作速度。采用新型结式晶体管构成很简单的驱动线路。这种存储器由四个容量为4096字的磁心体构成。为了缩短驱动电流的传输时间,每个磁心体单独进行驱动。
This article describes a current coincidence core memory, its capacity is 16384 words, each word is 27 bits. Cycle time is 1.2 microseconds, nominal switching time ≤ 0.6 microseconds. Using an annular ferrite core with an outer diameter of 30 mils, the temperature coefficient of the core is low, allowing working ambient temperatures up to 75 ° C without the need for ventilation. The structure of this memory drive and readout system is very simple, with a simple method to eliminate capacitive interference currents within the transformer matrix. Select the system and prohibit the use of the drive are suspended output drive. The sense amplifier's DC recovery is achieved by controlling its gain so that it does not reduce its operating speed. The new junction transistors form a very simple drive line. This memory consists of four magnetic cores of 4096 words. In order to shorten the drive current transmission time, each core body alone drive.
