Hello, I have the same chip as you ti046b1 chip (Serial I2C F-RAM) (Dell laser printer with almost dead toner cartridge)
I tried to read it with my raspberry Pi 3, so I connected SDA SCL VDD GND as shown in pictures, but when I run the command "i2cdetect -y 1" on my Raspberry it shows no device connected to I2C interface (empty) like that:
pi@raspberrypi:~ $ i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
do you have any idea to solve that ?
- I tried by inverting SDA SLC connections
- I tried by pulling-up to 3.3V SDA and SCL with 10k resistors (as stated

could you please help me to solve that ?
And to anticipate your first question : I checked all the connections for this wiring
