    electronics.stackexchange.com/questions/543374/what-is-scratchpad-memory

    Scratchpad memory isn't a "type" of memory. It is the purpose the memory is used for, but any type of memory could be used for that purpose. Semiconductor marketing of course picked up on this confusion long ago: if there's a "market", we shall fill it, and thus you had products designated as scratchpad (or cache!)

    electronics.stackexchange.com/questions/222514

    Implement scratchpad, cache and other internal book-keeping memory areas. Build bus peripherals such as I2C, SPI and memory interfaces and any other useful peripheral one can think! Build program counter, fetch circuits before you feed the instructions to the decoder.. Or build an instruction pipeline and some instruction parallelism

    Serial is an umbrella word for all that is "Time Division Multiplexed", to use an expensive term. It means that the data is sent spread over time, most often one single bit after another.

  5. What are the freeware SPICE simulators available?

    electronics.stackexchange.com/questions/1206

    Does anyone know of a freeware SPICE / circuit simulator? SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose, open source analog electronic circuit simulator. It i...

  6. What is the truth about 1.5 V "lithium" cells?

    electronics.stackexchange.com/questions/276540

    The wiki page for Lithium batteries has a list of many different chemistries and their voltages. A Lithium anode with an Iron Disulphide cathode (\$\mathrm{Li-FeS_2}\$) is one such example of a 1.5V terminal voltage, and is the chemistry used in the AA replacement batteries as per the datasheet link on the Wiki page, and in @pjc50's answer.
