M die is the standard. SK Hynix updates come from that initial sequence of digits, like the fourth from the end. For a 16Gb A die, the code would be "H5CG48AGBD," while a 16Gb M die would read "H5CG48MEBD" (details may vary with JEDEC standards). These codes are generally batch identifiers, not direct die labels—you can see actual 16Gb M die sticks with 126A on them. For reference, check the TechPowerUp reviews: the 16Gb A die has a photo here and the 16Gb M die here (Adata kit). Spoiler links provided.
