Dear jerson and mister e

i have rechecked my connections, they are correct. I dont know where is the problem. I have even grounded WP which i havent done before. One more technical aspect that i want to tell you that i have connect WP and A0 and A1 directly to ground i.e. no pull down resistors. IS this making the problem. If any one of you have a working circuit of 24C512 with PIC, please send it so that i can rechecked my connections. Please send me coding as well.
