Help me in all of this questions

Answer 1

given infermahen ram the imcge 13 addreus tines LAo-A The Memory chip a and a wE (te Enable ) oin and Oe (Output Enable) Read pin bothane actve lod Signalo So the erly mamary which as Wvite and Road operahons RAM CRandon Access Memovy) ROM only as OE Coutput Enable) So RAM is type of Memary used Ab we obsenved here Anc 13 address tines (Ao-A) f memory ehip add res 1ines memovy ze (Neof locatte) 13 8A k = 8K locatiory are thene Memy Sre

not given daa bus aize But we ane 8K locations 8192 locatins So Mamory Size : ifeoch location ab 13yre data than hen Memovy Size is 9192 Bytes we 3) F Correcty obsenve lhe whale eivauit gives hore 20 addres lines Ao- A a given to Mamory chip outof which Ao-A,2 ana wed for addrs decoding Ana Since the given memay hip ta a hagmeat in a iMB 20 RAM Memory (Sizez 2' IMB) Aa- A,s ane aiven to NAND when all ane high NANO PTo ducos a Low Sianal os output which Hhe ecode ohlch is aki drioing Ce Outpty2 disab bles with high mamy along wimput M/To dsable making memory nots itaibe enabled

1 o Since encoda auteut 2 i connacted to chip Sclet of Memary CCE 1) and provided input a to cE mahina he Memey chipto enable -A, con he bl oo0g o000,0 00 0o Minimum addrs O o oo O00o O OOOD Monumum Addros 1 (1 !! 1 0 Encoden NAND Input addres for chip Momry he loo output disables ed decoden So CE get low tohich maka Memory Chip get dletad
1) RAM

2) 8192 MEMORY LOCATIONS ( memory size =8K )

3 min address = FC000 ( hexadecimal )

Max address = FEFFF (hexadecimal)
