Abstract: Information of two categories (e.g. two different types of microprogram material) are written into respective stacks in a store, the stacks advancing towards each other from separate base addresses as information is added to them. In this way, the two categories of information share the same storage space, and the space is utilised in an efficient manner while preserving sequential addresses within the two categories. One stack has priority over the other. This is achieved by removing all the information in the lower priority stack when there is not enough room to add new information to the higher priority stack.

Abstract translation: 两个类别（例如两种不同类型的微程序材料）的信息被写入存储器中的相应堆栈中，当信息被添加到它们时，堆栈从单独的基地址彼此前进。 以这种方式，两类信息共享相同的存储空间，并且以有效的方式利用空间，同时保持两个类别内的顺序地址。 一个堆栈优先于另一个堆栈。 当没有足够的空间将新信息添加到较高优先级堆栈时，通过删除较低优先级堆栈中的所有信息来实现。
