Here’s an actual stick of RAM - with 8 memory modules soldered onto the board.

这是一块实际的 RAM - 板上焊接了 8 个内存模块。

In this case, the bottleneck is RAM. RAM is typically a memory module that lies outside the CPU.

在这种情况下，瓶颈是 RAM。 RAM 通常是位于 CPU 之外的内存模块。

Instead of thinking of this as a series of individual memory modules and circuits, we’ll think of it as a uniform bank of addressable memory.

我们不会将其视为一系列单独的内存模块和电路，而是将其视为统一的可寻址内存库。

After that, we’ll scale up, and build our very own memory module, and we’ll combine it with our ALU next time, when we finally build our very own CPU!

之后，我们将扩大规模，构建我们自己的内存模块，下次我们将把它与我们的 ALU 结合起来，最终构建我们自己的 CPU！
