If you are talking about RAM chips that only store 128 bytes of memory each (I know of no such chips), then you would need 8 of them.
128 = 27
1024 = 210
210 / 27 = 23
I'm not sure what "128 4" means, but if you mean you can store 128Bx4 on each chip, then you need 2 such chips.
To construct a RAM memory system of 2 bytes using 1288 RAM memory chips, first, determine the capacity of a single 1288 chip. Each 1288 chip typically has 128 bits (or 16 bytes). Therefore, to achieve 2 bytes, you would need 2 bytes / 16 bytes per chip = 0.125 chips. Since you cannot use a fraction of a chip, you would need at least 1 chip to construct the RAM memory system of 2 bytes.

2048/128 = number of chips.
Why do you want to waste 99.22% of the memory in these chips you supposedly will be spending good money on? Buy smaller sized memory chips more suitable for your purposes and design with them!
They can cause errors that hang the system.
Some graphics cards have memory on board the card itself. Others rely on the memory chips on the system board for memory , thus sharing memory. Suppose a PC has a specification of 256MB of memory and 64MB shared graphics. The memory available for your operating system and applications will be 192MB. If a PC had the same specifications but the 64MB were dedicated, the 64MB required to run the card would use this memory, leaving the full 256MB for your operating system and applications. In short, shared = compromise, dedicated = better.
The memory modules that include registers between the system's memory controller and the module's memory chips are known as Registered DIMMs (RDIMMs). These modules have a register that acts as a buffer, allowing multiple memory chips to communicate in parallel with the memory controller while sending data in series. This design helps improve stability and scalability in systems with larger amounts of RAM, as it reduces the electrical load on the memory controller. RDIMMs are commonly used in servers and high-performance computing environments.
Read Only Memory(ROM) Basic Input Output System(BIOS) or firmware chips are "Electrically Erasable and Programmable Read Only Memory(EEPROM)" chips, these kind of chips can be upgraded by flashing.
Poor-quality memory chips can cause many problems in a computer. These include causing all kinds of errors like those in applications, hanging system errors, and GPF errors.
Soldering the memory chips on a special circuit board refers to the process of permanently attaching the memory components to a printed circuit board (PCB) using a molten metal alloy (solder). This ensures reliable electrical connections and mechanical stability for the memory chips, which are essential for the functioning of electronic devices. The "special circuit board" implies that the PCB is designed specifically to support the memory chips and their integration into a larger electronic system.
Single-sided memory has memory chips on only one side of the module, while double-sided memory has memory chips on both sides. Double-sided memory typically has a higher memory capacity than single-sided memory due to more chips being present.
128x8=128 bytes 4096x16=4069x(8x2)=4096x2 bytes; hence, chips required, 4096*2/128=64; ans=64.
