Question about two-port and dual-port

[eexuke]

Two-port or dual-port?

Dear all,
I am rather confused about these two. I think both of them should have two separate address bus and data bus. But which one has single clock and which one has two clocks?
Thanks!

Hi eexuke,

Dual port means you can read & write the 2 ports(port A, port B).

Two port means one port is read only, another port is write only.

Dual port and two port can both have two clocks.
As specified by wadaye, Dual port can support the two read/write operation at the same time, but the two port can't.

the difference is : dual-port you can read and write at the same time
but two-port you can not do that
