What is DRAM?
DRAM, or dynamic random access memory, is a type of RAM (random access memory) which stores each bit of data into a separate capacitor in an integrated circuit. The capacitor can be discharged or charged and these two states represent the two values of a bit (0 and 1). It is the most common kind of RAM for PCs and workstations. With random access memory, a processor can directly access any part of the memory instead of proceeding sequentially from a given starting place. DRAM is ‘‘dynamic’’ because contrary to SRAM, or static RAM, the storage cells of DRAM need to be refreshed or given an electronic charge periodically due to charge leaks in capacitors. The advantage of DRAM resides in its simplicity: only one capacitor and one transistor are required per bit, instead of four or six transistors in SRAM.
Types of DRAMs
There are several different kinds of DRAM chips at Future Electronics. We stock many of the most common types categorized by several parameters including memory density, configuration, nominal supply voltage, CAS latency, speed grade and packaging type. Our parametric filters will allow you to refine your search results according to the required specifications.
DRAMs from Future Electronics
Future Electronics has a wide range of DRAMs from several chip manufacturers that can be used for a DRAM memory cell or any other types of dynamic random access memories. Once you decide if you need a component DRAM or a module DRAM, you will be able to choose from their technical attributes and your search results will be narrowed to match your specific DRAM application needs.
We deal with several manufacturers such as Alliance Memory Inc, Centon Electronics Inc., Renesas Electronics, Samsung or Unigen. You can easily refine your DRAM product search results by clicking your preferred DRAM brand from the list of manufacturers below.
Applications for DRAMs:
DRAM memories are high volume memories. Some DRAMs have high speed interfaces such as DDR and DDRII SDRAM, and some have speed enhancing internal architectures. DRAMs with low power internal design techniques are used in battery operated systems. Some DRAM memories are also used for graphics enhancements like high speed point-to-point interfaces as well as several internal graphics functions. DRAMs can also be used in networking and battery operated synchronous and asynchronous applications. The main memory (the random access memory) in personal computers is DRAM. DRAM is also the type of RAM used in workstations and laptop computers as well as some video game consoles.
Choosing the Right DRAM:
With the FutureElectronics.com parametric search, when looking for the right DRAMs, you can filter the results by category. We carry the following categories of DRAMs:
- Component DRAM
- Module DRAM
Once you choose the DRAM category, you can narrow them down by various attributes: by memory density, configuration, speed grade, nominal supply voltage and CAS latency to name a few. You will be able to find the right DRAM chip for a DRAM memory cell as well as other types of dynamic random access memories.
DRAMs in Production Ready Packaging or R&D Quantities
If the quantity of DRAMs you require is less than a full reel, we offer to our customers several of our programmable DRAMs in tray, tube or individual quantities that will help you avoid unneeded surplus.
Future Electronics also offers its clients a unique bonded inventory program designed to eliminate potential problems that may arise from an unpredictable supply of products that could contain raw metals and products with erratic or long lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
