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 ...

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 ...

SDRAM Controller For Low-end FPGAs

There are very few ‘recent’ FPGAs out there that can be easily soldered. Due to their important number of IOs, they usually come in Ball Grid Array (BGA) packages. The Xilinx Spartan 6 LX9, a TQFP144 ...

DDR FCRAM Boosts Performance In DDR SDRAM Designs

A modified form of synchronous DRAM technology, double-data-rate, fast-cycle random access memory (DDR FCRAM) is primarily focused at the networking market segment. Yet due to its high performance, it ...

DDR SDRAM Controller IP Designed for Reuse

This paper deals with reusability issues in the development of a double data rate (DDR) SDRAM controller module for FPGA-based systems. The development of integrated systems-on-a-chip (SoC) is based ...

SDRAM Chip Set Boldly Goes Where No Man Has Gone Before

When it comes to achieving more memory in the same amount of space, we typically talk about process shrinks, die stacking, multichip packaging, and other techniques. But MetaRAM, a fabless company ...
