I have a RAM with 8 TMS44400DJ chips on it. It says the word length is 1048576, so would it mean times 8 I have 8MB RAM on this module?

    \$\begingroup\$ Each chip is organized as 1 048 576 words of four bits each. i.e. 512 KiB. times 8 would only be 4MiB, I think. \$\endgroup\$ – AJN Jul 7 '20 at 12:53
  • \$\begingroup\$ Does it mean, having 4 chips, 1048576 words of 16 bits each I will end up with 8MB RAM? Would the general rule be: number of chips x words × (bits/8)? \$\endgroup\$ – Bartek Malysz Jul 7 '20 at 13:35

    \$\begingroup\$ you are overthinking this ... each chip is 4 bits wide ... you need 2 chips to make a byte .... so 2 chips make 1 MiB ... etc. etc. \$\endgroup\$ – jsotola Jul 7 '20 at 14:56
  • \$\begingroup\$ It is a 4Mb chip, where the 'b' means bit. 8 * 4Mbit = 32 Mbit = 4 Mbyte.(To be pedantic, all M's should be Mi) \$\endgroup\$ – Wouter van Ooijen Jul 7 '20 at 17:15
