IEDM 2009 Conference Report - D.Wouters, IMEC - WIND project distribution 1

General comments

• With over 30 high quality selected papers on memory, IEDM remains one of the top conferences on (Non-Volatile) Memory

• 6 Sessions do explicitely mention “memory” in their title

• Topics cover different types of NVM, with number of papers reflecting their importance (Flash > PCM > RRAM > MRAM > FRAM)

General/Invited• 27.7 Future directions of NVM in compute applications

(A.Fazio, intel)

Indicated memory market growth opportunities in a new market segment. Compute memory is an opportunity for NAND, with SSD replacing HDD. New (RRAM) memory technologies may even offer better (DRAM-like) performance (so called storage class memory) so that NVM may cover even more positions upfront in the memory hierarchy, but cost and scaling are still open issues!

Flash papers #14

• CT ~9• FG• 3D~3

A lot of papers on Flash, especially on Charge Trap Flash that is seen as possible scaling solution, either in 2D or in 3D (BICS) approach
