Memory Calculation Details

Memory in bytes is calculated by dividing the User Memory [bit] by 8 (since there are 8 bits in a byte).
Block Count is determined by dividing the Memory [Byte] by 4 (since each block consists of 4 bytes).

Example Calculation

ICODE 3 and ICODE 3 TagTamper:
- User memory: 2400 bits
- Memory in bytes: 2400 ÷ 8 = 300 bytes
- Block count: 300 ÷ 4 = 75 blocks
ICODE DNA:
- User memory: 2016 bits
- Memory in bytes: 2016 ÷ 8 = 252 bytes
- Block count: 252 ÷ 4 = 63 blocks
ICODE SLIX 2:
- User memory: 2528 bits
- Memory in bytes: 2528 ÷ 8 = 316 bytes
- Block count: 316 ÷ 4 = 79 blocks
