Abstract: The disclosed system causes power to be removed from the memory for a chosen time duration after each time that the memory is used. The time duration can be chosen as desired and is specified by a ''''WAIT N'''' instruction. When this instruction appears, the power to the memory is removed therefrom and accesses to the memory are prevented. The time duration is entered into a register and the contents of this register are compared with the contents of a counter which has a clock pulse train applied thereto until equality is attained whereby an equality signal issues. The latter signal is applied to restore power to the memory and, with appropriate logic, permits accesses to the memory, read or write, for example. When the memory accessing is completed, the N units specified by the ''''WAIT N'''' instruction would be usable at the option of the program to control access to the memory and to remove power therefrom for the duration of N time units. A new ''''WAIT N'''' instruction can change the time duration.

Abstract translation: 所公开的系统在每次使用存储器之后在所选择的持续时间内导致从存储器中去除功率。 可以根据需要选择持续时间，并由“等待N”指令指定。 当这个指令出现时，从存储器的电源被去除，并阻止对存储器的访问。 将持续时间输入到寄存器中，并将该寄存器的内容与应用了时钟脉冲序列的计数器的内容进行比较，直到达到相等性，从而产生相等的信号。 后一个信号被应用于恢复对存储器的电力，并且通过适当的逻辑允许例如访问存储器，读取或写入。 当存储器访问完成时，由“WAIT N”指令指定的N个单元将可用于该程序的选项，以控制对存储器的访问并且在N个时间单位的持续时间内从其中移除电力。 新的“等待N”指令可以改变持续时间。
