We don't need to wait, we already know that what he wrote there is absurd, completely wrong and even impossible to exist.
Just remember that this year Hot Chips already happened.
Let’s also remember that MS was the company that was so worried customers might think PS3 was more advanced than Xbox 2 they named the box 360 instead.
What I’m saying is MS know as well as anyone that the information they published at hot chips would be analysed just like Sony for Cerny’s presentation. Neither company is going give technical specifics if those specifics go against the marketing message and show a disadvantage to their product.
I don't think the SSD's DRAM is used to cache files..
“
SSDs will keep all or a portion of the map in DDR2 or DDR3 (usually). DRAM is much faster than NAND, so the SSD can access the map quickly to increase performance. DDR-type memory loses data when there isn't any power, but NAND stores it even when the power goes out. The SSD keeps a copy of the map on the NAND to reduce the chance that it will lose the map from a power loss. (Technically, the SSD doesn’t lose the data, it just loses the map, so it can't find it).
There are a few different approaches to eliminating DRAM. We only know of a few because the deep inner workings and algorithms tend to be closely held trade secrets. A common method is to build a small amount of memory into the controller. The Phison S11 controller we have in our tests pool features 32MB of SRAM built into the controller, but that is a very small amount of memory compared to an external module. Other techniques include compressing the flash translation layer map (essentially, it is a complicated spreadsheet, so it compresses easily) or caching a portion of the map in system memory (
HMB). The SSD controller accesses as little as 8 percent of the map frequently, so there are ways to reduce the performance loss.
Unfortunately, DRAMless SSDs also have a sinister side. Updating the map directly on the flash requires small random writes, which takes a bite out of the SSD's endurance. This is a particularly vexing issue with low endurance planar 2D TLC NAND flash. At Computex last June, one SSD vendor told us about an OEM 2D TLC SSD that will burn through the rated endurance in a little over a year. The SSD has to last a year because of the notebook's one-year warranty, but anything beyond a year's worth of use is up to the user to fix. Tactics like that are the driving forces behind putting cheap DRAMless SSDs in $500 notebooks.”
