Q. For the given circuit, which of the following is correct? 1 AO 1 A1 O A2 O A3 1 A4 O A5 1 A6 1 A7 RAM 256 X 4 A. The number 5 is being written to the memory at address location 203. B. The chip has not been enabled, since the EN terminal is 0; therefore, nothing will be written to the chip and the output is tri- stated. A 255 QC O DO 1 D1 O D2 1 D3 C. Decimal 10 is being written into memory Q= location 211. D. The read/write line is LOW; therefore, decimal 5 is being stored at memory O R/W O CS WRITE READ EN location 211. Data inputs Address inputs
