SDRAM Logic Analyzer Uses An AVR And A Dirty Trick

We often see “logic analyzer” projects which are little more than microcontrollers reading data as fast as they can, sending it to a PC, and then plotting the results. Depending on how fast the ...

SDRAM interface slashes pin count

Many designs need deep buffering but don't require ultrahigh-memory bandwidth. Examples include image and audio processing, as well as some deep-FIFO applications. These designs often use a single ×8 ...

Peering Into A Running Brain: SDRAM Refresh Analyzed From Userspace

Over on the Cloudflare blog, [Marek] found himself wondering about computer memory, as we all sometimes do. Specifically, he pondered if he could detect the refresh of his SDRAM from within a running ...

Performance differences between EDO DRAM and SDRAM?

If you're talking about EDO simms vs. SDRAM dimms you're comparing 60ns to 7ns RAM. Quite a difference. I'm not sure exactly how that translates in terms of real world performance. Someone with ...

The Love/Hate Relationship with DDR SDRAM Controllers

Almost everyone knows that the bulk of DRAMs produced end up in desktop and laptop computers just like the one used to write this article. In fact, approximately 90% of all DRAMs produced are used in ...

Are there any SDRAM to EDO converters

With the RAM prices the way they are, and the fact that I have to install EDO memory in pairs (it's cheaper to get 2 128MB PC133 DIMMS than 1 64MB EDO SIMM), I was wondering if there's any product ...
