Dynamic Random Access Memory (DRAM). Part 1: Memory Cell Arrays

preview_player
Показать описание
This is the first in a series of computer science videos is about the fundamental principles of Dynamic Random Access Memory, DRAM, and the essential concepts of DRAM operation. This particular video covers the structure and workings of the DRAM memory cell. That is, the basic unit of storage capable of storing a single binary digit, a 1 or a 0. You will see that a DRAM memory cell is comprised of a single pass transistor connected to a single capacitor. You will also see the way that these cells are arranged in a large rectangular array connected by thousands of bit lines and word lines. In addition, you will learn about the role of differential sense amplifiers when it comes to reading and writing data to such an array. In the videos that follow, you will find out more about the way DRAM cells are addressed, and how they are organised, so that it is possible to store bytes and words rather than just single bits.

00:40 : What is a memory cell and how is made?
3:50 : How are memory cells arranged together?
4:21 : How can you read the content of a cell?
8:25 : Why so much work for just reading a cell? Eheh
9:27 : Summary!

I appreciated the video 🤙

This series is beautifully done. I can only imagine the amount of work to create it.
One point of correction is at 9:21 refresh interval is stated to be 64 ns, but should be 64 ms.

Great video. I got it right away. Listening to Steve Wozniak talking about when DRAM started appearing and how they chose to go with it because it was cheaper, and how it had to be refreshed all the time, got me interested.

An excellent lecture that very clearly explains the structure and principles of a dynamic memory. I wish you will continue to do so for the benefit of humanity and especially for students and engineers who want to know better and understand the principles perfectly.

love how you start at the lowest level of abstraction and work your way up. Makes this content super digestable :)
