Does anybody know what's the defference between single-port SRAM and dual-port SRAM, as well as multi-port SRAM? Is there any documents for SRAM design? thanks a lot.
 

see the following link regarding dual port ram
 

Al Farouk, there is no following link posted!

Also:

i don;t understand multi-port RAM in the sense that i have not encountered generators for anything else than single- and dual-port.

In my designs i often use multiple-output register banks which is different.
I would like if some vendor provided SRAM-based configurable register banks.

Sorry for this mistake the link is
**broken link removed**

for me its also the first time to hear a bout multiport memory
 

signal port sram : has one address port;

two port sram: has two address ports;

multi port sram: has multiple address ports;

the ports mean how many path there are to access a ram array;

best regards

Two port SRAM: R/W data by 2 data bus which seperated control by 2 address, and reading or writing in 2 port simultaneously .
 

what prohibits reading and writing from/to the same location in memory at the same time ?
 

when r/w the same location, i think the logic is read the data come from write data bus not the RAM
