Do Yoy/Did You Remember?

silak12Hi! everyone,Could you tell me the difference between these two?
'Did you remember me? refers to the past

Do you remember me? refers to the present

Can you tell me about those two do you remember the name of the most important thing

True 'Did' is past tense. You are referring to something that has already occurred e.g. 'Did you remember me when you spoke at the meeting yesterday?'
In contrast, 'Do you remember me' is present tense. You would ask this question in present time, now time. If you went up to someone you may have met previously you could ask this question.
