Data Memory Access Times
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
CPU cycles as described in Figure 7-3.

EEPROM Data Memory
The ATmega328P contains 1K byte of data EEPROM memory. It is organized as a separate
data space, in which single bytes can be read and written. The EEPROM has an endurance of at
least 100,000 write/erase cycles. The access between the EEPROM and the CPU is described
in the following, specifying the EEPROM Address Registers, the EEPROM Data Register, and
the EEPROM Control Register.
“Memory Programming” on page 286 contains a detailed description on EEPROM Programming
in SPI or Parallel Programming mode.
