    not sure what you are asking. right beside the SRAM macro you don't place anything, it's empty space left that way on purpose for routing signals in/out and for power isolation.
    on the macro itself, you usually have periphery cells that guarantee the bitcells are not influenced by any weird layout next to it.
    Really, I am not Sam.

    Generally Endcap cells are placed around the memories .
    There are two different kinds of endcaps which are placed , top-bottom endcaps and left-right endcaps . Top-bottom endcaps are responsible for providing well continuity to the standard cell on the site rows above the endcaps , whereas left-right endcaps are responsible to guide the fab lab the end of site rows. Generally a margin is given in conjugation of hard blockages before placing the endcaps.
