Course Description

102-Memories in Computers — Part 1: Overview and DRAM Introduction

Modern computers include many types of memories, including magnetic hard drives, Flash memories, Static Random Access Memories (SRAM) and Dynamic Random Access Memories (DRAM). The characteristics, advantages and limitations of each of these memory implementations are described and compared. The most important of these memory types is DRAM, and this course takes you inside the DRAM so you can understand how it operates and why it is the largest selling integrated circuit ever invented.

DRAMs were a $38B (USD) business in 2010, and appear in every computer (PC, Mac, tablet, laptop, desktop, server or mainframe) and home gaming console (PlayStation, Xbox or Wii). DRAMs first appeared on the scene in 1970, introduced by a small start-up company called Intel. Today they are a commodity, produced by companies all over the world in essentially interchangeable form.

Both the original DRAM architecture, called the asynchronous DRAM, and the higher speed synchronous version, the SDRAM, are discussed in detail. You will be introduced to the concepts of refreshing, access time, multiplexed addresses, fill frequency, CAS latency and burst length. No math beyond simple arithmetic is required.

The course was good with the history and overview information, but could use some updating - especially in the DRAM sizes and costing.

A bit dated but very informative on giving a good back ground on the subject matter.

Always enjoy dipping my toe in an electronic/electrical field of study in which I have little experience in order to taste what other engineers have to tackle. A lot of fun.

The course is hard to follow for two reasons: text too small & explanation is difficult.
All of our courses are produced in a standard 12-point font. You control the magnification on your own computer. Look for ZOOM!

One of the best on line courses I have ever taken. The structure of the questions really made me dig to understand the subject matter. I will take Courses 2 and 3 in the future.

The only reason I did not give 5 stars was because the material is dated to 2010 era and I know tremendous advances have been made since then. I hope the next two courses fill in that gap.

For a non-E.E. the course was OK. The illustrations on the memory operations were a little difficult to follow. The test had some curve balls but that's understandable.
