大容量的存储器生产良率一般不高,这会直接影响到芯片的生产良率,本文使用冗余设计,使得芯片内部放置多块存储器,即使其中有一块或者多块有问题,未能通过测试,只要芯片中其余正确的存储器满足一定条件,通过校准和特定配置,也不会影响整个芯片的使用。提高了芯片的生产良率,降低了芯片的成本。 Large-capacity memory production yield is generally not high, which will have a direct impact on the production yield of the chip, this article uses redundant design, making the chip to place multiple pieces of memory, even if one or more of them have problems, failed to pass the test , As long as the remaining correct memory in the chip to meet certain conditions, through calibration and specific configuration, it will not affect the use of the entire chip. Improve the production yield of the chip, and reduce the cost of the chip.
