SRAM Peripherals

Hi
the sram read and write operation is only performed when enable is high or not ?
in this sram array circuit, they have not used row enable. is CE (chip enable ) here working same as row enable [ left bottom corner of the image shown ].

thanks

Don't think that the diagram has much to do with actual transistor level implementation.

Hi,

the sram read and write operation is only performed when enable is high or not ?

The pictrure shows 3 "enable" signals:
* CE: chip enable. Always needed for R and W access. It wakes up the internal circuitry (low power sleep vs active)
* WE: write enable. Used to tell tha chip that you want to store data into the SRAM
* OE: output enable. Usec to drive the data (bus) lines. High-Z vs Output. High-Z so that other devices can drive the data lines.

than you for the response @KlausST, if CE is performing the wake up operation then what does enable signal do in the ROW decoder?

what does enable signal do in the ROW decoder

Look at your picture. There is no enable input to the row decoder.
