Hi all,

We have several eMMC IC,SDIN5D2 ,SDIN7DP2, they are all 4G-Sandisk parts.But we want to know which technology used.I mean how to know it is 19nm or 24nm or 32nm technology by chip marking.

Another way, which CMD can read part informaiton and wafer technology by SW.

Thanks in advance.

Best regards
