New Book: Vertical 3D Memory Technologies

Wiley has recently published a new book by Betty Prince titled Vertical 3D NAND Technologies that is one to consider if you want to bring yourself up to speed on recent research behind today’s and tomorrow’s 3D memory technologies.

For those who haven’t previously encountered Dr. Prince, she is the author of a number of key books covering memory design and holds memory patents written over her 30-year career in the field.

The book provides capsule summaries of over 360 papers and articles from scholarly journals on the subject of 3D memories, including DRAM, NAND flash, and stacked chips.

These papers are organized into Continue reading “New Book: Vertical 3D Memory Technologies”

Fundamentals of Memory – Free Online Course

Some time ago The Memory Guy was asked by Numonyx (later acquired by Micron) to put together an online course for EE Times on memory technologies, explaining how each one works and where it is used.

Although the course was very well received, I never posted a link to it on The Memory Guy blog. This post is intended to correct that error.

The course runs 75 minutes and covers the basics of DRAM, non-volatile RAM, SRAM, NAND flash, NOR flash, mask ROM, and EEPROM. It explains each technology’s advances in size, cost and performance, leading up to the development of Continue reading “Fundamentals of Memory – Free Online Course”

SanDisk’s Amazing 512GB SD Card

SanDisk has introduced an SD Card with a whopping 512 gigabytes of storage. Noting that SD Card capacities have increased by 1,000 times over the past ten years, from 512MB to 512GB, the company says that this product is aimed at professional HD videographers (who can justify its $800 price) allowing them to shoot Raw-format footage without shutting their cameras off, which could potentially allow them to miss a magic moment.

To The Memory Guy this represents an amazing piece of packaging technology. Let’s see why:

In 2003 SanDisk’s 512MB card contained Continue reading “SanDisk’s Amazing 512GB SD Card”
