三星将在2022 VLSI上发表18篇论文
VLSI研讨会将于6月12日至17日在檀香山的希尔顿夏威夷村举行。三星将在会议上发表18篇论文。
其中在DRAM存储器类别中,三星将发表 "A 16 GB 1024 GB/s HBM3 DRAM with On-Die Error Control"。
三星的第三代10纳米DRAM(1z)具有更高的系统可靠性、可用性和可维修性(RAS)的性能,主要针对汽车、工业和数据中心应用。
为此,他们采用了一种新的片上纠错(ECC)方案,可以同时纠正16位字错误和2个单独位错误,并将其纳入新版 "高带宽内存-3"(HBM3)DRAM中。

在每个单独的DRAM芯片上进行本地修正,而不是访问堆栈中的其他部分,从而减少了延迟,并将引脚数据速率从上一代的5Gb/s/引脚提高到8.0Gb/s/引脚,使每个内存的总内存带宽达到1024GB/s。并在一个16GB的DRAM模块中得到了证明。

三星的3纳米栅极环绕FET(GAA FET)技术在 "A 3nm GAAFET Analog Assisted Digital LDO with High Current Density for Dynamic Voltage Scaling Mobile Applications "中得到了展示。
这里讨论了模拟辅助数字LDO,它提供了高电流密度的电力输送,该设计具有主动的电源噪声消除和CPU内核的快速瞬态负载检测。

这种混合LDO设计在<1 mA到1.4 A的负载范围内实现了精确的调节,在1 ns内对1 A的动态负载只有38mV的电源下降。

此外,还有一篇关于 "A 0.6μm Small Pixel for High Resolution CMOS Image Sensor with Full Well Capacity of 10,000e- by Dual Vertical Transfer Gate Technology"的论文。
三星公司利用双垂直转移门(D-VTG)技术,开发了一种使用0.6μm像素的200Mp图像传感器原型,其全电荷井容量(FWC)为10,000e。与单垂直转移门相比,D-VTG的FWC增加了60%,并且由于转移门电压的可控性提高,转移性能也得到了改善。
