When performing a read of the 5th cell from the top (the first cell is at Address 5C20h):

1) The Read Data input must be set to__________________

2) The Write Data input must be set to_______________

3) The Address bus must be set to________________ h

In response, the memory will output on the____________bus the binary number (_________)₂ corresponding to the hexadecimal number___________h.

When performing a write of the value 41h in the 2^nd cell from the top (the first cell is at Address F200h):

1) The Read Data input must be set to_________

2) The Write Data input must be set to__________

3) The address bus must be set to________________h

4) The data bus must be set to_____________h

In response, the cell initially containing the binary number (________ )₂ will be overwritten with the binary value (___________)₂

Answer 1

1.1) .The Read Data input must be set to 11000111

1.2) . The Write Data input must be set ..... /////as it is read operation

1.3). The Address bus must be set to 5C24h

1.4). In response, the memory will output on the__Data bus_bus the binary number (11000111)2 corresponding to the hexadecimal number 0xD7h.

2.1) The Read Data input must be set to ////as it is write operation

2.2) The Write Data input must be set to 00100001

2.3) The address bus must be set to F201h

2.4) The data bus must be set to 00100001

In response, the cell initially containing the binary number (00010101)2 will be overwritten with the binary value (00100001)2
