Especially, these days, the distinction between them is very confusing..

For example, NVidia's shared memory is 32-banked, so what they say is in one cycle, 32 data can come out at the same time... then what is port ? also same issues to cache structure

Could anyone clarify on this ? Thanks!

The term "bank" is generally used to refer to a group of essentially identical items -- a memory bank, a bank of disk drives, etc.

The term "port" refers to a conceptual hole or pipe through which something passes. Generally this applies to I/O devices and the like.

A "port" is a signal or set of signals that connect directly and exclusively from one group of electronics to another group, usually between distinct electronic components/circuits. A "bank" is a set of devices, ports, or buses that may be addressed individually or as a group.
