TSSOP8 (DW)

169 mil width

The M34C02 is a 2 Kbit serial EEPROM memory

able to lock permanently the data in its first half

(from location 00h to 7Fh). This facility has been

designed specifically for use in DRAM DIMMs

(dual interline memory modules) with Serial

Presence Detect. All the information concerning

the DRAM module configuration (such as its

access speed, its size, its organization) can be

kept write protected in the first half of the memory.

This bottom half of the memory area can be write-

protected using a specially designed software

write protection mechanism. By sending the

device a specific sequence, the first 128 bytes of
