Eeprom; Is there a schematic?

I am Googling I2C tutorials to get a good grasp of the protocol. I wanted to see a schematic of non-volatile memory bit addresses. For that matter, I'd like to see a schematic of Propeller RAM at the bit level. I think it helps to look under the hood.

    I have uploaded the data sheet for a 2114 1K x 4 ram chip. It is a very old chip, but it is the only data sheet I have that shows anything about address decoding. All of the random access memory chips (ram, eprom, eeprom, fram, etc.) perform address decoding in a similar manner. Even the I2C use the same address decoding internally. The major difference is that I2C chips shift the address in to a serial to parallel register instead of providing all the address bits to the chip in parallel.

    Kwinn, Thanks for the info. I'm imagining millions of mosfets and flip flops. It won't help me program. I'm just curious about how binary data is manipulated at the component level.

    I know what you mean. I prefer to understand the "nitty gritty details" rather than just knowing a device as a "black box" that performs a specific task. You are right in imagining millions of mosfets and flip flops.
