中国制造的DDR5内存芯片比三星的DDR5芯片大近40%——芯片制造技术较不先进China-made DDR5 Memory Chips are Nearly 40% Larger Than Samsung's DDR5
<p>➀ 中国内存制造商长鑫存储技术(CXMT)开始出货DDR5内存芯片,但它们的晶圆尺寸比三星的大40%;<br>➁ 更大的晶圆尺寸是由于使用了较不先进的芯片制造技术;<br>➂ CXMT的16 Gb DDR5晶圆尺寸与第一代DDR5芯片相当;<br>➃ CXMT的DDR5成本可能比美光、三星和SK海力士高;<br>➄ 大晶圆尺寸表明CXMT在工艺技术方面比竞争对手落后几年。</p><p>➀ China-based memory maker ChangXin Memory Technologies (CXMT) began shipping DDR5 memory chips, but their die size is 40% larger than Samsung's; <br>➁ The larger die size is due to the use of less advanced chipmaking technology; <br>➂ CXMT's 16 Gb DDR5 die size is comparable to first-generation DDR5 chips; <br>➃ CXMT's DDR5 costs are likely higher than Micron, Samsung, and SK hynix; <br>➄ The large die size indicates CXMT is years behind in process technology compared to competitors.</p>
