CHIPSET - 82359 DRAM(Dynamic Random Access Memory) RAM memory which essentially consists of a tiny capacitor for each bit of memory. Since capacitors do not hold a charge indefinitely, DRAM must be constantly refreshed to avoid losing its contents. Also, the process of reading the contents of the memory are destructive, meaning extra time must be spent restoring the contents of memory addresses which are accessed, so DRAM is slower than SRAM. See also Refresh, SRAM. CONTROLLER {#idx133819}{#idx133821}{#idx133983}{#idx133985}{#idx133994}{#idx134008}{#idx134037}{#idx134043}{#idx134049}{#idx134053}{#idx134062}{#idx134067}
