7. TAG MEMORY AND ISSUES REQUIRING ATTENTION
A.
EPC C1G2 TAG
(
G2 TAG
)
Tag memory shall be logically separated into four distinct banks, each of which may comprise zero or more
memory words. The four storage areas:
Reserved memory (password memory)
shall contain the kill and and/or access passwords, if passwords are
implemented on the Tag. The kill password shall be stored at memory addresses 00h to 1Fh; the access password
shall be stored at memory addresses 20h to 3Fh.
EPC memory
shall contain a Stored CRC at memory addresses 00h to 0Fh, a Stored PC at addresses 10h to
1Fh, a code (such as an EPC, and hereafter referred to as an EPC) that identifies the object to which the Tag is or
