DRAM Basics – Why This Memory Technology Is Indispensable

DRAM, or dynamic random access memory, stores each bit of data in tiny capacitors built into intricate integrated circuit chips. Unlike technologies like flash memory, DRAM chips need frequent electrical charges to prevent data loss, hence the "dynamic" terminology.

This volatile nature means DRAM lacks non-volatile flash memory‘s advantage for long term data retention. However, the structural simplicity of DRAM memory cells gives it key strengths maximizing density and speed that has made DRAM the go-to choice for system memory across electronics:

Key DRAM Characteristics

  • Ultra high memory density facilitating large capacities
  • Very fast data access times (as low as 10 ns)
  • Low cost per GB relative to other options
  • Low power demands allowing extensive miniaturization

With these vital attributes, DRAM has proven extremely scalable allowing single modules to hold tens of gigabytes densely packed into tiny form factors. And despite periodic market consolidations between DRAM vendors, steady manufacturing improvements have made DRAM pricing decline consistently over decades:
