Hi Prasad .

SRAM 256 * 8 - here 256 = no. of addressable locations .
8 = No. 0f bits stored per address .

If u multiply both u get size of the memory .

256*8
means SRAM consists of 256 rows with each row consisting of 8 bits. So the RAM size is 2k(256*8 ) with 8 bit (2^8=256) address lines and data line is 8 bit.
