External EEPROM write/read problems (Arduino Uno) - arduino

Question

I have Arduino Uno(Atmega328p) and external EEPROM connected via I2C.
My code in Arduino Studio:
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define OLED_MOSI 9
#define OLED_CLK 10
#define OLED_DC 11
#define OLED_CS 12
#define OLED_RESET 13
Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);
#define EEPROM_ADDR 0x50
#include <M24AA01.h>
M24AA01 dev(0);
byte data[1] = {1};
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
display.begin(SSD1306_SWITCHCAPVCC);
writeEEPROM(1);
uint8_t readData = readEEPROM(1);
display.clearDisplay();
display.setTextColor(WHITE);
display.setTextSize(1);
display.setCursor(5,30);
display.print("read:");
display.print(data);
display.display();
}
void loop() {
// put your main code here, to run repeatedly:
}
void writeEEPROM(unsigned int eeaddress)
{
Wire.beginTransmission(EEPROM_ADDR);
Wire.write((int)(eeaddress >> 8)); // MSB
Wire.write((int)(eeaddress & 0xFF)); // LSB
Wire.write(data[0]);
Wire.endTransmission();
delay(5);
}
uint8_t readEEPROM(unsigned int eeaddress)
{
uint8_t rdata = 0xFF;
Wire.beginTransmission(EEPROM_ADDR);
Wire.write((int)(eeaddress >> 8)); // MSB
Wire.write((int)(eeaddress & 0xFF)); // LSB
Wire.endTransmission();
Wire.requestFrom(EEPROM_ADDR,1);
if (Wire.available()) rdata = Wire.read();
return rdata;
}
My physical connection of the EEPROM:
PIN 1: A0 - 5V(VCC)
PIN 2: A1 - 0(GND)
PIN 3: A2 - 0(GND)
PIN 4: VSS - 0(GND)
PIN 5: SDA - SDA
PIN 6: SCL - SCL
PIN 7: WP - 0(GND)
PIN 8: VCC - 5V(VCC)
I have a DIP version of EEPROM.
From the documentation I read that address of EEPROM is 0x50 (1010000). A0 is connected to 5V, but anyway A0,A1,A2 are "dont cares" as per documentation, so I believe address is fine.
No matter what I write to the EEPROM, in this case I just write 1 byte of data (number 1) - it reads 255.
One thing I noticed is that I do not specify in the code if I want to write or read (in documentation the 8th bit is read/write bit, read = 1, write = 0), but I do not know how to use it in code.
