But memory cells jump into action to make new virus-fighters if an infection sneaks in.

但是，如果感染潜入，记忆细胞就会开始行动，制造新的抗体。

Memory cells are a special part of the immune system.

记忆细胞是免疫系统的一个特殊部分。

After we zoom out a little, you can see that the memory cells are stacked vertically.

稍微缩小一点后，您可以看到存储单元是垂直堆叠的。

Rockefeller University researchers found those memory cells may become stronger and able to target more diverse kinds of the virus after the third shot.

洛克菲勒大学的研究人员发现，这些记忆细胞可能会更变得更加强大，并且在第三针后能够针对更多种类的病毒。

Most memory cells in 2020 can hold 8 different levels, but newer technology can have 16 different levels of electrons.

2020 年的大多数存储单元可以容纳 8 种不同的级别，但新技术可以容纳 16 种不同的电子级别。

But some of the clonally expanded cells live on as memory cells and they're ready to expand once more if that pathogen ever resurfaces.

但一些克隆扩增的细胞会作为记忆细胞存活下来，以待病原体下一次露面时再次扩增。

Let's review some terminology: this a memory cell and this is a string.

让我们回顾一些术语：这是一个存储单元，这是一个字符串。

A page is around 30,000 to 60,000 adjacent memory cells wide.

一页大约有 30,000 到 60,000 个相邻的存储单元宽。

Let's move on and explore how these memory cells are organized so that we can store more than just 3 bits of information.

让我们继续探索这些存储单元是如何组织的，以便我们可以存储超过 3 位的信息。

Here we have the arrays of 3D memory cells, the row decoder and the page buffer at the bottom.

这里，我们有 3D 存储单元阵列、行解码器和底部的页缓冲器。

Doing some quick multiplication we find that there are 3,840 memory cells here capable of storing a total of 11,520 bits.

进行一些快速乘法运算我们发现这里有 3,840 个存储单元，总共能够存储 11,520 位。

This stack of memory cells, what is technically called a string is composed of 10 charge trap flash cells layered one top of another.

这种存储单元堆栈，技术上称为串，由 10 个电荷捕获闪存单元层叠而成。

The same kinda sequence happens when charges are being added to a charge trap which is how information is written to a memory cell.

当电荷被添加到电荷陷阱时，也会发生同样的序列，这就是信息被写入存储单元的方式。

Well, in each cell we can store information by placing different levels of electrons onto a charge trap, which is the key component inside the memory cell.

好吧， 在每个单元中， 我们可以通过将不同级别的电子放置到电荷陷阱上来存储信息，电荷陷阱是存储单元内部的关键组件。

These charge trap flash memory cells are stacked into strings 10 cells tall, which are duplicated into pages of 32 strings in a row.

这些电荷捕获闪存单元堆叠成 10 个单元高的字符串，这些字符串被复制成一行 32 个字符串的页面。

Sometimes it was the inadvertent misfiring of memory cells that happens to us all; at other times he was spinning his own version of reality both to me and to himself.

有时，这是我们每个人都会有的因疏忽引起的记忆错误，但有些时候，乔布斯则是在向我也向自己，编织在他头脑中的现实印象。

So once you've had something like chicken pox or mumps or measles, you'll always have some memory cells ready to make more antibodies if they see that infection again.

所以一旦你得了水痘、腮腺炎或麻疹，你总会有一些记忆细胞准备好制造更多的抗体， 如果他们再次看到这种感染。

Here's a single sheet of paper so you can get a sense of the of the approximiate height of these stacks of memory cells.

这里有一张纸，您可以通过它了解这些存储单元堆栈的大致高度。

It's here that we can see the memory cells that are used in every single one of your smartphones or tablets, as well as inside the solid-state drive in your computer.

在这里，我们可以看到你的每一部智能手机或平板电脑中使用的存储单元，以及你的计算机中的固态硬盘内部的存储单元。

The antibodies float around your bloodstream for a while and then can diminish, but blueprints on how to make them are stored in specialized memory cells, waiting for future Napoleons to invade.

抗体会在您的血液中漂浮一段时间，然后会逐渐减少，但是有关如何制造它们的蓝图存储在专门的记忆细胞中，等待未来的拿破仑入侵。
