there is pdf file for Micron TLC memory with following data:
Page Size: 16384+2208 bytes
Pages Per Block: 1536
Block Size: 27888 kB = (16384+2208)*1536
Is MX300's Erase Block Size 27888 kB?
What number 2208 means?
I think you'd ignore the 2208. That would be for internal use I guess - error checking and recovery and such like.
Then you'd end up with 24MB block size which matches what's stated here: http://www.tomshardware.co.uk/micron-3d-nand-flash,news-52385.html
