一 | 8月26日消息,三星宣布,全球首次研发出面向移动端及端侧AI设备的下一代内存——LPDDR-PIM,该技术将运算功能集成于移动内存中,可有效提升AI处理速度并降低功耗。

二 | At least 189 decomposing bodies have been removed from a Colorado funeral home, much higher than initial reports suggested when the story surfaced earlier this month, according to the Colorado Bureau of Investigation.The Return to Nature Funeral Home based in Colorado Springs, Colorado, offers environmentally friendly burials but came under investigation after more than 115 human remains were found being improperly stored on the property, according to a statement from the Fremont County Sheriff’s Office from earlier this month.Responding to a suspicious incident, authorities found around 115 decomposing bodies stored inside a space of about 2,500 square feet. The bodies were in such bad condition that they will need to be identified through DNA, officials said.However, a statement issued on Tuesday by the Colorado Bureau of Investigation on behalf of Fremont County Sheriff Allen Cooper and Fremont County Coroner Randy Keller confirmed the body count to be much higher than originally thought.“On October 13, 2023, all decedents were removed from the Return to Nature Funeral Home in Penrose. The effort was coordinated by the Fremont County Coroner’s Office with support from several entities,” the CBI said. “Teams removed at least 189 individuals and transported them to the El Paso County Coroner's Office. The total number of decedents could change as the identification and investigative processes continue.”Families will be notified once bodies can be identified but the DNA testing could take months, according to local officials."Without providing too much detail to avoid further victimizing these families, the area of the funeral home where the bodies were improperly stored was horrific," Cooper said earlier this month.The scene was so bad when authorities first arrived that that a paramedic who responded developed a rash and had to be medically evaluated, Cooper said.“We are conducting extensive coordination efforts as we focus on the identification of the decedents and provide notifications to ensure the families are given accurate information to prevent further victimization as they continue to grieve their loved ones,” said Fremont County Coroner Randy Keller.Authorities did not disclose what the funeral home was doing with the human remains but did confirm that they are working with the Fremont County Coroners' Office, the Colorado Bureau of Investigation, the Colorado Department of Regulatory Agencies, the Colorado Department of Public Health and the FBI on the case."Green Burial is a natural way of caring for your loved one with minimal environmental impact. Green Burial aids in the conservation of natural resources, reduction of carbon emissions and the preservation of habitat, WITHOUT the use of harsh embalming chemicals, metallic, plastic or unnatural items," the website for the funeral home says. "You can still view your loved one who is NOT embalmed. Embalming is NOT a law. In the state of Colorado within 24 hours the body must be either embalmed or placed in a regulated temperature controlled environment, meaning under refrigeration, dry ice, etc."Officials said they are now beginning the second phase of their investigation on Tuesday.“The second phase of this comprehensive process includes confirming identification and completing family notifications,” the CBI said. “Family notifications will be conducted by a team led by the Fremont County Coroner’s Office, victim advocates and others and this is expected to begin in the next several days.”There is currently no timeline for completion of the investigation.。

在美国斯坦福大学举行的半导体学术会议Hot Chips 2026上,三星相关负责人首度公开展示了LPDDR5X-PIM的结构、规格及验证结果——该产品本月初刚在FMS 2026内存会议上斩获下一代内存奖项,但详细参数直到此次会议才正式披露。 PIM(内存内运算)技术通过在内存中嵌入运算单元,使部分计算可直接在内存内部完成,无需像传统架构那样将数据频繁搬运至CPU或GPU再传回内存。 对于AI运行而言,数据搬运是主要性能瓶颈之一,应用PIM后,简单运算就近处理,从而在提升速度的同时显著降低功耗。
在测试环节,三星以参数规模达80亿的Meta开源AI模型Llama 3.1为基准,结果显示LPDDR5X-PIM的处理时间为5.4秒,较普通LPDDR5X的12.3秒快了约2.3倍;每秒令牌处理量达81.3 TPS,为现有产品27 TPS的三倍。 事实上,三星早在2021年便公布了面向高带宽内存的HBM-PIM技术并完成开发验证。此次将PIM落地于智能手机等移动设备广泛采用的LPDDR低功耗内存,正是顺应大语言模型向小型化、高效化演进的新趋势。

四 | 相关负责人指出,虽然HBM是目前AI内存的标准方案,但并非所有场景都非它不可,LPDDR-PIM兼具高带宽与低功耗,为端侧AI开辟了新的可能。
随着生成式AI直接在智能手机、PC等终端设备上运行的端侧AI趋势不断扩展,LPDDR-PIM的应用前景持续看涨——电力与空间受限的移动设备,亟需在提升AI算力的同时严控功耗。 在兼容性方面,该产品沿用与通用LPDDR相同的阵列设计,无需大幅改动系统即可部署。目前,三星正提供软件开发工具包和模拟器等资源,积极推动生态建设。

五 | 继LPDDR5X-PIM之后,三星已启动LPDDR6-PIM的标准化工作,AI内存竞争正从以HBM为中心的数据中心,延伸至智能手机和PC等端侧领域,内存也正从单纯的数据存储设备,向直接参与运算的关键组件演进。
