ABB PFEA112-65 3BSE050091R65 具有4096位寬度的內(nèi)存總線

HBM實現(xiàn)了更高的帶寬，而功耗卻比DDR4或者GDDR5。[7]這是通過堆疊多達八個來實現(xiàn)的動態(tài)隨機存取存儲器?死亡和測試邏輯的可選基底管芯。[8]堆棧通常連接到內(nèi)存控制器國家政治保衛(wèi)局。參見OGPU或者中央處理器穿過諸如硅的襯底插入式選樣。[9][10]或者，內(nèi)存芯片可以直接堆疊在CPU或GPU芯片上。在堆疊中，管芯通過以下方式垂直互連硅通孔(tsv)和微凸塊。HBM技術(shù)在原理上類似，但與不兼容混合存儲立方體(HMC)界面開發(fā)人員微米技術(shù)。[11]

與DDR4或GDDR5等其他DRAM存儲器相比，HBM存儲器總線非常寬。四個DRAM芯片(4 Hi)的HBM堆棧每個芯片有兩個128位通道，總共有8個通道，總寬度為1024位。因此，具有四個4-Hi HBM堆棧的顯卡/GPU將具有4096位寬度的內(nèi)存總線。相比之下，GDDR內(nèi)存的總線寬度是32位，帶有512位內(nèi)存接口的顯卡有16個通道。[12]HBM支持每包高達4 GB。
