Bu teknoloji, \u201chibrit kazan\u0131ml\u0131 h\u00fccre belle\u011fi<\/strong>\u201d veya hybrid gain cell memory<\/strong> (i\u00e7erik devam\u0131nda HGCM olarak k\u0131salt\u0131lacak) olarak adland\u0131r\u0131l\u0131yor ve SRAM<\/strong> ile DRAM<\/strong>\u2019in avantajlar\u0131n\u0131 bir araya getirerek \u00f6zellikle depolama yo\u011funlu\u011funu art\u0131rmay\u0131 hedefliyor. <\/figure>\n

Elektrik M\u00fchendisli\u011fi Profes\u00f6r\u00fc Philip Wong\u2019un liderli\u011findeki ara\u015ft\u0131rma ekibi, GPU’larda kullan\u0131lan SRAM <\/strong>tabanl\u0131 \u00f6nbelleklerin, nispeten yava\u015f olan DRAM<\/strong>\u2019den veri y\u00fcklemek zorunda kalmas\u0131 nedeniyle ya\u015fanan bir \u201cbellek duvar\u0131 problemi\u201d oldu\u011funu belirtiyor. Bu ge\u00e7i\u015fin \u00e7ok fazla zaman ve enerji t\u00fcketti\u011fi ifade edilirken, geleneksel SRAM\u2019e k\u0131yasla daha iyi performans \u00f6zelliklerine sahip bir teknolojinin geli\u015ftirilmesi gerekti\u011fi vurgulan\u0131yor.<\/p>\n

SRAM ve DRAM\u2019in kapasite sorunlar\u0131<\/b><\/p>\n

G\u00fcn\u00fcm\u00fczde modern \u00e7iplerde SRAM, b\u00fcy\u00fck bir alan kaplamas\u0131 ve bir bitlik veriyi saklamak i\u00e7in d\u00f6rt transist\u00f6re ihtiya\u00e7 duymas\u0131yla kapasite a\u00e7\u0131s\u0131ndan s\u0131n\u0131rlay\u0131c\u0131 bir fakt\u00f6r haline geliyor. Buna kar\u015f\u0131l\u0131k DRAM, ayn\u0131 i\u015fi tek bir transist\u00f6r ve ek bile\u015fenlerle yapabiliyor. Ancak DRAM, depolanan verilerin s\u00fcrekli yenilenmesi gerekmesi gibi dezavantajlarla kar\u015f\u0131 kar\u015f\u0131ya.<\/p>\n

<\/span> Hibrit kazan\u0131ml\u0131 h\u00fccre belle\u011fi teknolojisi, her iki belle\u011fin en iyi \u00f6zelliklerini tek bir \u00e7\u00f6z\u00fcmde birle\u015ftirmeyi ama\u00e7l\u0131yor<\/strong>. Yeni teknolojinin en \u00f6nemli \u00f6zelli\u011fi, verileri depolamak i\u00e7in ayr\u0131 okuma ve yazma transist\u00f6rlerine sahip olmas\u0131 ve DRAM\u2019in \u00e7al\u0131\u015fmas\u0131 i\u00e7in gerekli olan ek kapasit\u00f6r ihtiyac\u0131n\u0131 ortadan kald\u0131rmas\u0131. Wong\u2019un ekibi, iki farkl\u0131 malzemeden yap\u0131lan transist\u00f6rler <\/strong>kullan\u0131yor: yazma transist\u00f6r\u00fc i\u00e7in indiyum kalay oksit (ALD ITO), okuma transist\u00f6r\u00fc i\u00e7in ise silikon PMOS. Bu \u00e7\u00f6z\u00fcm, iki silikon oksit bazl\u0131 transist\u00f6rden daha performansl\u0131 bir se\u00e7enek olarak \u00f6ne \u00e7\u0131k\u0131yor. <\/figure>\n

Yeni teknolojide performans \u00e7ok y\u00fcksek<\/b><\/p>\n

<\/span> Yeni bellek teknolojisi performans olarak da iddial\u0131. Yap\u0131lan testlerde, bu teknoloji ile \u00e7al\u0131\u015fan bir cihaz\u0131n verileri 1 saatten fazla s\u00fcre saklayabildi\u011fi<\/strong> g\u00f6zlemlendi. DRAM\u2019in her 64 milisaniyede bir yenilenme ihtiyac\u0131 g\u00f6z \u00f6n\u00fcne al\u0131nd\u0131\u011f\u0131nda, bu b\u00fcy\u00fck bir fark yarat\u0131yor. Ayr\u0131ca, veriler DRAM\u2019den 50 kat daha h\u0131zl\u0131<\/strong> okunabiliyor; eri\u015fim s\u00fcreleri ise 1 ile 10 nanosaniye aras\u0131nda de\u011fi\u015fiyor. <\/figure>\n

Ancak bu \u00fcst\u00fcn performans \u00f6zellikleri, her zaman ger\u00e7ek d\u00fcnyada daha iyi performansa d\u00f6n\u00fc\u015fm\u00fcyor. Ara\u015ft\u0131rma ekibi HGCM teknolojisinin baz\u0131 durumlarda SRAM\u2019den daha yava\u015f olabilece\u011fini, \u00f6zellikle de daha y\u00fcksek veri yo\u011funlu\u011funa sahip yap\u0131land\u0131rmalarda bu yava\u015fl\u0131\u011f\u0131n ya\u015fanabilece\u011fini belirtiyor. Her ne olursa olsun, HGCM teknolojisinin en \u00f6nemli \u00f6zelli\u011fi, d\u00fc\u015f\u00fck seviyeli \u00f6nbellekler i\u00e7in \u00e7ok \u00f6nemli olan daha y\u00fcksek depolama kapasitesi sunabilmesi. Daha b\u00fcy\u00fck \u00f6nbellekler, CPU veya GPU\u2019nun sistem DRAM\u2019inden veri aktarma s\u00fcresini k\u0131saltarak performans\u0131 ve gecikme s\u00fcrelerini iyile\u015ftirebilir. Esas\u0131nda bu prensip, AMD\u2019nin 3D V-Cache teknolojisinin temelini olu\u015fturuyor.<\/p>\n\n
