Ars Technica heeft vandaag deel 1 van hun Ram Guide online gezet. Dit deel behandeld de basis van DRAM en SRAM: hoe gegevens opgeslagen, opgevraagd en georganiseerd worden. Zeker een interessant artikel, en deel 2 wordt nog een stuk leuker: daar worden ook de meer exotische geheugen typen zoals Fast Page, EDO en SGRAM behandeld :
It's long been a truism that, no matter what kind of system you have, the best way to get the biggest performance increase for the least money is to buy more RAM. All enthusiasts know how important RAM is to system performance, but the bewildering array of RAM types on the market today makes buying RAM a challenge. SDRAM, EDO DRAM, Fast Page DRAM, RDRAM, and a myriad of other RAM types face the upgrader or the new buyer. The wide variety of RAM flavors coupled with the fact that RAM isn't quite as glamorous as CPUs or video cards makes RAM one of the least understood parts of a system. Quite often, people know the main differences between an Athlon and a PIII, or between the GeForce and the ATI Rage. When it comes to RAM, however, most people would be stumped if you asked them to explain the difference between CAS 2 and CAS 3.
The situation doesn't have to be this way, though, because all of these types of RAM share certain features that make them easier to understand if you can apprehend a few basic concepts. Here in the first part of the Ars Technica RAM Guide, I'll do my best to explain the basic concepts and technologies that underlie most modern varieties of system RAM. Part I will cover SRAM and asynchronous DRAM, while later parts will tackle more complex types of DRAM like Fast Page, EDO, and SDRAM as well as more exotic RAM technologies like RAMBUS and SGRAM.
