Hi all,

Anyone has designed Dual Port SRAM using 2 single port SRAM?

Please give references.
Thanks,

single-port dual-port sram difference

1. You can use TWO single port RAMs to generate a dual-port RAM: one for even address and another one for odd address.
 

sram single port

divide the address into 2 parts.
e.g
4 width address.0000 ~ 1111

0000~0111 can be the first ram's address
and 1000~1111 can be the second ram's address.

so. the MSB is the enable signal of each ram.
when 0 , ram 1 is enabled
when 1, ram 2 is enabled
 

Thanks for your replies.

But what I need is true Dual Port SRAM. In-a-sense read and write to two different ports can happen simultaneously.

Wht explanation you have provided just adds the depth of SRAM kind of address concatination.

Thanks,
Gold_kiss
