We don’t want to have to deal with all the individual logic gates... so as before, we’re going to bump up a level of abstraction, and put our whole Gated Latch circuit in a box -- a box that stores one bit.

我们不想处理所有单独的逻辑门… … 所以和以前一样，我们将提高抽象级别，并将整个门控电路放在一个盒子里——一个储的盒子一点。

We only want the latch at the intersection of the two active wires to be enabled, but all of the other latches should stay disabled.

我们只想让两条活跃线路交叉处的启用，而其他所有的应该保持禁用状态。

By adding a few extra logic gates, we can build this circuit, which is called a Gated Latch since the " gate" can be opened or closed.

通几个额外的逻辑门，我们可以构建这个电路，它被称为门控，因为这个“门”可以打开或关闭。

Now we can put a 1 on the data line to save the value 1 to our latch.

现在我们可以将数据线上的值设为1，以将值1保到我们的中。

The key to making this a useful piece of memory is to combine our two circuits into what is called the AND-OR Latch.

将这两个电路组合成所谓的与或，是使这段内变得有用的关键。

So the address for the particular latch we just used can be written as 11001000.

所以，我们刚刚使用的那个的地址可以写成11001000。

So, today, we built a piece of SRAM - Static Random-Access Memory – which uses latches.

所以，今天，我们构建了一块静态随机取储——SRAM，它使用了。

For 256 bits, we need a 16 by 16 grid of latches with 16 rows and columns of wires.

对于256比特，我们需要一个16乘16的网格，包含16行和16列的电线。

A group of latches operating like this is called a register, which holds a single number, and the number of bits in a register is called its width.

像这样运作的一组称为寄，它放一个单一的数字，而寄中比特的数量称为其宽度。

The latch we just saved our one bit into has an address of row 12 and column 8.

我们刚刚保了一个比特的，其地址是第12行第8列。

That should only ever be true for one single latch at any given time.

那在任何时刻只会对单一的一个成立。

We can use the same trick with a read enable wire to read the data later, to get the data out of one specific latch.

我们可以使用相同的技巧，通一根读使能线在稍后读取数据，从而从一个特定的中获取数据。

Because only one latch will ever be write enabled, only one will ever save the data -- the rest of the latches will simply ignore values on the data wire because they are not write enabled.

因为只有一个会被启用写入，所以只有它会保数据——其余的会忽略数据线上的值，因为它们没有被启用写入。

This is called a " latch" because it " latches onto" a particular value and stays that way.

这被称为“”，因为它会“定”一个特定的值并保持不变。

So we can use this signal to uniquely select a single latch.

所以我们可以使用这个信号来唯一选择一个。

To activate any one latch, we must turn on the corresponding row AND column wire.

要激活任何一个，我们必须打开对应的行和列线。

Luckily we only need 1 wire to enable all the latches, but that’s still 129 wires.

幸运的是我们只需要一根线来启用所有的，但那仍然是129根线。

To write to our register, we first have to enable all of the latches.

要向寄写入数据，我们首先必须启用所有的。
