DRAM\u2019in SSD \u0130\u00e7indeki Rol\u00fc<\/h2>\n\n\n\n

SSD\u2019nin beyni olarak nitelendirilen kontrolc\u00fc, veriyi depolama h\u00fccrelerine yazmak ve oradan okumak i\u00e7in karma\u015f\u0131k i\u015flemler ger\u00e7ekle\u015ftirir. DRAM, kontrolc\u00fc ile NAND flash aras\u0131nda \u00e7al\u0131\u015fan bir k\u00f6pr\u00fc gibidir. Mant\u0131ksal adreslemeyi fiziksel h\u00fccre konumlar\u0131na d\u00f6n\u00fc\u015ft\u00fcren haritalar, s\u0131k kullan\u0131lan veri bloklar\u0131 ve kontrolc\u00fcn\u00fcn y\u00f6netim verileri DRAM\u2019de saklan\u0131r. Bu sayede her okuma veya yazma iste\u011finde do\u011frudan NAND\u2019a gitmek yerine, \u00f6nce \u00e7ok daha h\u0131zl\u0131 olan DRAM\u2019e ba\u015fvurulur.

    DRAM ile NAND flash aras\u0131ndaki en \u00f6nemli ayr\u0131m u\u00e7uculuk ve h\u0131zd\u0131r. DRAM, enerji var oldu\u011fu s\u00fcrece veriyi nanosaneye yak\u0131n gecikmeyle saklarken, NAND veriyi kal\u0131c\u0131 tutar ancak eri\u015fim s\u00fcreleri mikrosaniye mertebesindedir.
