Sequential Read Problem in AT24C512C

[nis2311]

I am using external I2C EEPROM 24C512. In that Page Write , Byte Write and Random Read are working fine. My problem is Sequential Read. when I initiate for Sequential Read, the first address of the data reading properly following next address - data's are not reading only getting 0xFF. But when i read in randomly means it reading fine. I given 1 ms to 5 delay also for next address read but problem remains same. Pull-up Resistors 4K7. Help me to solve this problem.

My Program:-

        Start();
	Write_Byte(0xA0);
	Ack();
	Write_Byte(0x00);
	ack();
        Write_Byte(0x00);
	Ack();
	Start();
        Write_Byte((0xA1);
	Ack();
        Data_1=Read_Byte();
	Ack();
        Data_2=Read_Byte();
	Ack();
        Data_3=Read_Byte();
        N_Ack();
	Stop();

in this Data_1 is Correct others are Wrong Value means 0xFF
