we were there long before nCache.....

" nCacheTM is a large, non-volatile write cache."

Perhaps some day e.Digital will visit how the attributes of a large non-volatile memory are utilized as a main memory in Sandisks consideration.

Basically what they are doing is replacing the normally associated DRAM....and utilizing it as non volatile main memory.... They say they removed the volatility of the DRAM from the arrangement, but how do they interface it?

It makes no difference where they place non-volatile memory....it's how they are using it that counts.

I/O to the nCache .....somewhere along the line there will be a volatile I/O consideration, there is no way around it....e.Digital has reduced this volatile hindrance to the smallest limits of the memory it is serving.... and they friggin patented the idea.

Sandisk either has status quo DRAM directive considerations...ie.FAT on the I/O of the nCache, or they are doing what e.Digal is doing without directive structures, along with a specifically sized volatile type SRAM cache.

nCache would be considered redundant in comparison to what e.Digital can do with 1 nonvolatile memory regarding fault tolerance. The only data at risk is what is contained in the tiny pass through cache.

Something volatile definitely sits in combination with the nCache....what is it?
