This is a simple way of reading eMCP hynix part number:
ex : H9TP 32 A 8 JDACPR-KGM
Digit 5 - 6 is Nand density in Gigabit = 32
1byte=8bit, so 32Gigabit = 4 Gigabyte (32/8=4)
Digit 8 in RAM density, also in Gigabit = 8
8Gigabit = 1Gigabyte
So in above example Hynix eMCP is have 4GB storage, and 1GB Ram size.
And you can search the other brand of eMCP with same nand and ram density.
Gud Luck 😉
