NETSOL S7S4418U4M
The S7S4436U4M and S7S4418U4M are 150,994,944-bits Quadruple Synchronous Pipelined Burst SRAMs. They are organized as 4,194,304 words by 36bits for S7S4436U4M and 8,388,608 words by 18bits for S7S4418U4M. The Quadruple operation is possible by supporting DDR read and write operations through separate data output and input ports with the same cycle.| Part No. | S7S4418U4M |

FEATURES
● 1.8V+0.1V/-0.1V Power Supply.● DLL circuitry for wide output data valid window and future fre- quency scaling.
● I/O Supply Voltage 1.5V+0.1V/-0.1V for 1.5V I/O, 1.8V+0.1V/ -0.1V for 1.8V I/O.
● Separate independent read and write data ports with concurrent read and write operation
● HSTL I/O
