In-System Reprogrammable Flash Program Memory
This section describes the different memories in the ATmega644. The AVR architecture has two
main memory spaces, the Data Memory and the Program Memory space. In addition, the
ATmega644 features an EEPROM Memory for data storage. All three memory spaces are linear
and regular.
The ATmega644 contains 64 Kbytes On-chip In-System Reprogrammable Flash memory for
program storage. Since all AVR instructions are 16 bitsor 32 bits wide, the Flash is organized as
32/64 × 16. For software security, the Flash Program memory space is divided into two sections,
Boot Program section and Application Program section.
The Flash memory has an endurance of at least 10,000 write/erase cycles. The ATmega644
Program Counter (PC) is 15/16 bits wide, thus addressing the 32/64K program memory loca-
tions. The operation of Boot Program section and associated Boot Lock bits for software
protection are described in detail in

SPI pins or the JTAG interface.
Constant tables can be allocated within the entire program memory address space (see the LPM
– Load Program Memory instruction description.
