Will you plug flash into your memory bus?

Why or why not?  Anyone else trying to enable this?

Don't know much about the NAND FLASH technology; But the first thought that occurs to me is the numbers of write/erase cycles that could be allowed for a NAND FLASH before it loses its capability for reliable operation. Is that number high enough as compared to DDR SDRAM? If FLASH is written/erased so frequently as like SDRAM how long it will last compared to a SDRAM?

Otherwise it will be great to have NV memory in place of the volatile memory...can get rid of batteries/super caps for implementing battery-backed memory.

Newer class of NVMs are coming - as a matter of fact, they are already in production - such as Phase Change Memory (PCM) which take the cycling capability of NV memory into millions of cycles.

Micron link, Msoft is key

Here's the link to Micron's plans for NVDIMMs I could not finmd earlier:
2013-02-07Flash will ride DRAM bus in 2014, says Micron
Micron notes support under Windows is key for this approach

@Sanjob: Endurance of flsash relative to DRAM remains an issue though flash chips and their controllers have made significant progess in this area.

@ccvv: Yes it will be facinating to see which of the array of new contenders takes over--or maybe we will wind up with a much more diverse world in memories.

Hay.

  if we have the programs stored in flash on the same bus as the dimm,

     then we dont need to spend all that time moving executable blocks  from drive to memory to run them, execute in place.

'just' need the code to know how to execute in place and only write to the flash when needed,

now that WILL speed things up, 

sounds fantastic,

@an_m: You got it, and I suspect that's just one of many implicaitons people will be discovering. There's a lot of new software to be written.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
