Question:

What is the data/bit error rate of the S34ML01G1 / S34ML04G1 NAND FLASH family series of products?

 

Answer:

The ECC requirement of any system is dependent on the Chipset employed within the target application. Therefore, the data or bit error rate regarding the S34ML01G1 / ML04G1 NAND FLASH family series cannot be accurately determined due the fact of the high quality characteristic of one-bit ECC.

The lower bit ECC requirement, the lower data/bit error rate.Conversly, the higher bit ECC requirement, the higher the data/bit error rate. As an example, if the target application produces four data/bit errors, then obviously a NAND FLASH device using one one-bit ECC is not suitable and will not be of any use.

A NAND FLASH using four-bit ECC is more suitable in this scenario. Cypress currently offers both one-bit and four-bit ECC. However, as mentioned previously, the ECC requirement is certainly dependent on the chipset used within the target application.
