I'm not quite following what you are asking here. If you're asking what versions of MySQL support the MEMO field data type the answer is that all hosting providers are using versions of MySQL that support it. MySQL supports it using the TEXT data type and there are four different types:
TinyText
Text
MediumText
LongText
If that is not what you are asking, I'm sorry I mis-understood your question.
