DDR3 SDRAM

Double Data Rate 3 (DDR3 SDRAM) - yuqori tarmoqli interfeysga ega sinxron dinamik tezkor kirish xotirasi (SDRAM) boʻlib, undan 2007-yildan beri foydalaniladi.

Avlodlari

2012-yil sentabr oyida JEDEC DDR4 ning yakuniy spetsifikatsiyasini chiqardi^[1]. DDR3 ga nisbatan DDR4 ning asosiy afzalliklari orasida soat chastotalarining yuqori standartlashtirilgan diapazoni shuningdek, ma'lumotlarni uzatish tezligi^[2] kiradi.
