- DRAM errors in embedded systems
- why live with it?why not design an interrupt driven program that functionally tests all memory a little at a time and all functional units, and have this constantly running in the background accumulating data. Statistically a DRAM error would eventually become visible even if it was a minor timing error...

- DRAM errors in embedded systems
- DRAM errors are just a problem for main memory: they also afflict embedded subsystems, like disk controllers, that use DRAM. Where are the problems and what can you do? by Robin Harris

- DRAM error rates: nightmare on DIMM street
- Windows.Atleast From Vista has a Utility in Administrative tools in the control panel.Where in "About this Mac"?I'd just like to make sure I know the right place to look for errors. I look under "Hardware/Memory" and see a list of all 8 DIMM slots. There's a column for...

- DRAM error rates: Nightmare on DIMM street
- A two-and-a-half year study of DRAM on 10s of thousands Google servers found DIMM error rates are hundreds to thousands of times higher than thought -- a mean of 3,751 correctable errors per DIMM per year. This is the world's first large-scale study of RAM errors in...

- Terabit 3-D chips will keep the flash party rolling
- more than three years ago...flash was replacing DRAM more than 3 years ago... I don't know exactly what you mean by "economic competitor" but seeing as flash has many advantages over DRAM, even if it was more expensive, it was a comparable competitor. And I had a flash BIOS mobo......

- Will flash DIMMs replace disks or DRAM?
- Where do you get drivers for booting off the SO-DIMM?I'm pretty sure that's not an option in the BIOS.Best guess, there would be a BIOS rewrite.An alternative would be (depending on the BIOS provider/vendor) that they would use a Linux BIOS implementation (examples: HyperSpace from Pheonix Technologies Pheonix BIOS...

- Will flash DIMMs replace disks or DRAM?
- Flash-based DIMMs open another front in the flash war on older storage technologies - this time against DRAM. When they hit the market, will it be DRAM or disks that take the hit? by Robin Harris

- Give your system a mid-life kicker
- If the economy has made you put off buying a faster system, you aren't alone. The good news: you can make your current system much snappier with faster storage - DRAM and disk. Here's how - and why. Your CPU speed is fixed. So is your network...

- The many-core performance wall
- Many-core chips are the great hope for more performance but Sandia National Lab simulations show they are about to hit a memory wall. How bad is it? Some background Memory bandwidth is the limiting performance factor in CPUs. If you can't feed the beast it stops...

- News on flash: EcoRAM held up as less power-hungry option than DRAM for server farms
- Most people I know who talk tech associate flash memory with mobile phones and other small handheld gadgets, but the technology now is emerging as an option for reducing the power requirements in massive server farms, especially those that are frequently called upon to serve up data quickly and often....

- A 16 GB DIMM

- Efficient Use of Memory Bandwidth to Improve Network Processor Throughput
- This paper considers the efficiency of packet buffers used in packet switches built using Network Processors NPs. Packet buffers are typically implemented using DRAM, which provides plentiful buffering at a reasonable cost. The problem addressed in this paper is that a typical NP workload may be unable to utilize the...

- Analysis of the PASR Standard and Its Usability in Handheld Operating Systems Such as Linux
- With companies now producing Low Power DRAM for handhelds, a new feature was developed called Partial Array Self Refresh PASR. This feature enables the DRAM to retain state in only part of memory, thus further reducing the self-refresh power. If handheld operating systems could use this feature, they could potentially...

- Building MEMS-Based Storage Systems for Streaming Media
- The performance of streaming media servers has been limited by the dual requirements of high disk throughput to service more clients simultaneously and low memory use to decrease system cost. To achieve high disk throughput, disk drives must be accessed with large IOs to amortize disk access overhead. Large IOs...
