Memory Design Insights: Technology Focus - BiCS FLASH

In my last post, I talked about how Toshiba Memory is enabling the development of products that keep pace with the fast-moving storage market. With our flash memory solutions, products that have yet to be conceptualized have the possibility to become a reality. Because our portfolio was purposefully designed to support applications that require a variety of features – including high reliability, high temperature, high performance and high endurance – we’ve got something for everyone.

  • Looking for high density? Our 3D BiCS FLASH™ offers up to a 512Gb (64GB) die. Note: that’s with TLC (triple-level-cell). An even denser package is enabled with QLC (quadruple-level-cell) technology. Keep reading!
  • Need to affordably achieve higher capacities? Not only does our QLC BiCS FLASH boost single-chip memory capacity to the highest level yet achieved1, it’s a lower dollar per gigabyte solution. 
  • Want even more capacity? With QLC BiCS FLASH, a 16-die stacked architecture in a single package realizes a capacity up to 2.66TB.

How are we able to continually innovate and introduce such forward-thinking solutions?  The short answer is that we are committed to investing in manufacturing - and addressing data storage challenges. At our Yokkaichi location, we operate one of the world’s largest and most advanced flash memory fabrication facilities. And recently, we broke ground on a new fab in Kitakami, Japan dedicated to the production of 3D flash memory.

Not only do our fabs make the leading-edge technologies of the future possible, they also enable us to support customers whose products rely on current technology.

Definition of capacity: Toshiba defines a Gigabit (Gb) as 1,000,000,000 bits, a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB =230= 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
