Topic: High memory


  
  Memory
Memory chips therefore need to be operating at something like 20ns to keep up, assuming that the CPU needs only one clock cycle for each one from the memory bus; one internal cycle for each external one.
Interleaved memory, which divides memory into two or four portions that process data alternately; that is, the CPU sends information to one section while another goes through a refresh cycle; a typical installation will have odd addresses on one side and even on the other (you can have word or block interleave).
Memory addresses on a PC are 20 bits long, and are calculated by shifting the contents of a 16-bit register 4 bits to the left, and adding it to a 16-bit offset.

 High Memory Area - HMA
Short for High Memory Area, HMA is the first 64KB (65,520 bytes) of extended memory above the first 1MB of memory found on IBM compatible computers.
The HMA can be used to swap programs from conventional memory into HMA causing the computer to think more conventional memory is available on the computer.
Additional information about the PC memory as well as a diagram can be found on RAM Diagram page.

 Feature: High Memory In The Linux Kernel
The virtual address is passed to the MMU (Memory Management Unit of the processor) which converts it to the proper physical address based on the tables set up by the kernel.
Memory in the ZONE_NORMAL region is mapped by the kernel in the upper region of the linear address space.
I/O Devices cannot directly address high memory from PCI space, so bounce buffers have to be used.

 SOCcentral: Solving High-Speed Memory Interface Challenges with Low-Cost FPGAs (SOCcentral 13248)
Large, fast memory devices are required in networking and communications applications, with tasks ranging from simple address lookups to traffic shaping/policing to buffer management.
DQS is generated from the differential clock fed to the DDR memory and a DLL inside the DDR memory is used to generate and align DQS to outgoing data.
Although a DDR memory does not use the differential input clock to launch or capture data, the DQS signal that is used is related to the incoming clock frequency.

 Samsung launches new flash high-power memory chip
The 16-gigabit NAND flash memory chip, equivalent to 2 gigabytes of storage, doubles a chip Samsung introduced in September 2004.
The development means more mobile devices can use flash memory instead of hard drives, which can fail if dropped suddenly or produce skips in music if used in high-motion activities such as running.
Flash memory, which can save data even when power is switched off, is most often used in electronic devices such as MP3 players, digital cameras and key chain drives.

 Kernel comparison: Improved memory management in the 2.6 kernel
The 2.4 Linux kernel had facilities to understand fairly large amounts of memory, but many changes were made to the 2.5 kernel to make it able to handle larger amounts of memory in a more efficient manner.
In the Linux memory manager, page tables keep track of the physical pages of memory that are used by a process, and they map the virtual pages to the physical pages.
This low memory is limited to the first 896 MB of physical memory and required for use by most of the rest of the kernel as well.

 High Blood Pressure Causes Memory Lapse?
"It's not that people with high blood pressure suddenly lose their memory, but they are slightly inferior in doing tasks that require them to pay attention and remember things for brief periods compared to those with normal blood pressure readings," says researcher J. Richard Jennings, PhD, of the University of Pittsburgh.
This "slower" brain activity -- which may be attributed to so-called "senior moments" characterized by occasional memory lapses that occur after age 50 -- was noted at similar levels in all the hypertensive patients he evaluated, no matter their age.
The participants were between ages 50 and 70 and none had been treated with high blood pressure medication when the study began.

Tiled memory blocks will not cross 64K boundaries, so the data in them can be used in 16-bit programs.
If you create a fixed-size heap, the initial block of memory must be large enough to satisfy all allocation requests made to it.
The heap uh the block is from, the block to be returned, and its size are passed to release_fn by _uheapmin or _udestroy.

 Feature: High Memory In The Linux Kernel   (Site not responding. Last check: 2007-10-23)
Besides, physical memory allocated to processes can all be accessed by the kernel, while kernel private data strutures stored in certain physical memory pages is invisible to processes, otherwise any process can mess up the kernel.
It is not necessary to have 3 GB of physical memory to map it all.
It makes implementing a 'physical memory file' device driver very easy, I would think, provided you are only interested in the bottom 1GB of the physical memory.

 Quick things to check when you experience high memory levels in ASP.NET
But, in general, high memory is when see that your Aspnet_wp.exe process (Internet Information Services (IIS) 5.0) or W3wp process (IIS 6.0) memory is consistently increasing and is not returning to a comfortable level.
Once the memory level is higher than that, we are performing less than we should be, and this may affect other applications running on the system.
One reason for high memory that we see here in Support a lot is when you have debugging, tracing, or both enabled for your application.

 CIOL : News : High-stakes memory chip trial kicks off   (Site not responding. Last check: 2007-10-23)
A verdict is expected to be issued in mid-April, and if Rambus wins, the jury could order Hynix, the second-biggest memory chip maker in the world, to pay hundreds of millions of dollars in back licensing fees and damages.
The case is being closely watched in the $20 billion-a-year DRAM industry because Rambus has similar suits pending with other memory chip makers such as No. 1 Samsung Electronics, also of South Korea.
Hynix is expected to argue that either its memory chips do not violate Rambus patents or that U.S. authorities erred in granting the patents.

 Extremely High Memory Usage - Ubuntu Forums
Can anyone tell me where the memory leak/resource hog is and if they're experiencing a similar situation (especially if you're running Hoary, but not from the PR CD).

If memory usuage is high and swap low, then I believe that is normal (if not, I'm sure someone will correct me).

 'The Thought of High Windows': Memory of Evil
Lynn Kositsky's The Thought of High Windows borrows from the true story of the Chateau de la Hille, a French castle where a hundred Jewish children refuged after the Kristallnacht in late 1938.
