摘要

几乎每个人都同意，冗余所提供的2000% -2000%的良率提高使其成为RAM制造商经济可行性的必要条件。但是，在重要的短期问题上存在相当大的争议:64K DRAM应该有冗余吗?保险丝应该用电脉冲还是激光脉冲来编程?冗余是否会对可测试性和/或可靠性产生不利影响?……这些和相关的问题将由小组成员进行评估。

Redundancy in RAMs

Virtually everyone agrees that the 200%-2000% yield improvement offered by redundancy makes its acceptance a necessity for the economic viability of RAM manufacturers. But, there is considerable controversy over important short-term issues: Should the 64K DRAM have redundancy? Should fuses be programmed by electrical or laser pulses? Will redundancy have an adverse effect on testability and/or reliability? . . . These and related issues will be assessed by the panelists.
