<p><em><span>技术和制造工艺的进步为3D NAND的演进另辟蹊径</span></em></p>
<p><span>2020</span><span>年</span><span>2</span><span>月</span><span>10</span><span>日，北京</span><span>——</span><span>西部数据公司</span><span><span> </span>(NASDAQ: WDC)</span><span><span> </span></span><span>日前宣布</span><span>已成功开发第五代3D NAND技术</span><span>——</span><span>BiCS5，</span><span>继续</span><span>为行业提供先进</span><span>的</span><span>闪存</span><span>技术来巩固其业界</span><span>领先</span><span>地位。</span><span>BiCS5基于</span><span>TLC</span><span>和</span><span>QLC</span><span>技术构建</span><span>而成</span><span>，以</span><span>有竞争力</span><span>的成本提供了</span><span>更高</span><span>的容量</span><span>、性能和可靠性。</span><span>在</span><span>车联网、移动设备和人</span><span>工智能等相关</span><span>数据</span><span>呈现</span><span>指数</span><span>级</span><span>增长</span><span>的当下</span><span>，BiCS5</span><span>成为了理想的选择</span><span>。</span></p>
<p><span>基于</span><span>5</span><span>12 G</span><span>b</span><span>的</span><span><span> </span></span><span>BiCS5 TLC，</span><span>西部数据</span><span>目前</span><span>已</span><span>成功</span><span>在</span><span>消费级</span><span>产品</span><span>实现量产</span><span>出货</span><span>。预计到2020下半年，BiCS5</span><span>将</span><span>投入</span><span>大规模</span><span>量产</span><span>。</span><span>西部数据</span><span>将推出</span><span>一系列容量</span><span>可选</span><span>的</span><span>BiCS5</span><span><span> </span></span><span>TLC和BiCS5 QLC</span><span>，</span><span>其中</span><span>包括</span><span>1.33 T</span><span>b</span><span>。</span></p>
<p><span>西部数据存储技</span><span>术与制造部门高级</span><span>副总裁Steve Paak</span><span>表示：“随着</span><span>又</span><span>一个十年</span><span>的到来</span><span>，新的3D<span> </span></span><span>NAN</span><span>D</span><span>演进</span><span>对</span><span>于继续</span><span>满足</span><span>数据量的</span><span>不断增长</span><span>和性能的</span><span>需求</span><span>都</span><span>至关重要。</span><span>BiCS5的成功</span><span>生产体</span><span>现了西部数据在闪存技术</span><span>方面</span><span>的持续领导地位</span><span>，以及</span><span>对</span><span>长期路标</span><span>的高效执行力。通过利用多层存储孔技术</span><span>来</span><span>提高</span><span>存储</span><span>密度</span><span>增加存储</span><span>的</span><span>层</span><span>数</span><span>，</span><span>我们</span><span>显著</span><span>提高</span><span>了3D NAND</span><span>的容量和性能</span><span>，从而不断满足</span><span>用户</span><span>期待</span><span>的</span><span>高</span><span>可靠性和</span><span>低</span><span>成本</span><span>。</span><span>”</span></p>
<p><span>BiCS5采用了</span><span>广泛的新技术和创新的制造工艺，</span><span>是</span><span>西部数据</span><span>迄今为止最</span><span>高密</span><span>度</span><span>、最先进的</span><span>3D NAND</span><span>。第二代多层存储孔技术</span><span>、</span><span>改进</span><span>的</span><span>制造</span><span>工艺</span><span>流程以及</span><span>其他3D NAND单元</span><span>的</span><span>增强功能</span><span>，</span><span>显著提高了整个</span><span>晶圆</span><span>水平</span><span>面</span><span>单元</span><span>的</span><span>阵列密度。</span><span>这些“横向扩展”技术</span><span>与112层垂直存储能力相结合，使BiCS5</span><span>相比于</span><span>西部数据</span><span>上一代</span><span>的96层BiCS4技术</span><span>，</span><span>其</span><span>每</span><span>片晶圆</span><span>的存储容量提高了40%*以上，同时优化了成本。新的设计改进还提高了性能，使得BiCS5的I/O性能比BiCS4</span><span>提升</span><span>了50</span><span>%</span><span>**</span><span>。</span></p>
<p><span><span>BiCS5</span></span><span><span>是与其技术和制造伙伴</span></span><span><span>铠侠株式会社</span></span><span><span>（</span></span><span><span>Kioxia Corporation</span></span><span><span>）</span></span><span><span>共同研发，将会在日本三重县四日市和日本岩手县北上市的合资工厂生产。</span></span></p>
<p><span>依托</span><span>BiCS5技术</span><span>，</span><span>西部数据</span><span>将推出</span><span>基于</span><span>3D</span><span><span> </span></span><span>NAND技术</span><span>的</span><span>个人电子产品、智能手机、IoT设备和数据中心</span><span>等</span><span>全方位系列产品</span><span>。</span></p>
