Many times, often hear people say "memory particle", in fact, this is Taiwan memory chip of a name (memory only), other chips, RTHK is called "chip", the meaning of the two is the same, as to how we call, look at personal habits.
Memory particles are an important part of the memory, the memory particles will directly affect the size of memory and the memory system is good or bad. Therefore, a good memory must have good memory particles to guarantee. At the same time, different manufacturers of memory granular system, performance, there are certain differences, the general common memory particle manufacturers have spotlight, Infineon, Samsung, Hyundai, South Asia, Mao Si and so on.
Meaning explanation

The main meaning of the above code:
1th-chip function K, representing the memory chip.
2nd bit-chip type 4, represents DRAM.
3rd-chip's further type description, S on behalf of SDRAM, H on behalf of the DDR, G on behalf of Sgram.
4th, 5-bit-capacity and refresh rate, the same size of memory with different refresh rate, will also use a different number. 64, 62, 63, 65, 66, 67, 6a represent 64mbit capacity, 28, 27, 2a capacity for 128mbit, 56, 55, 57, 5a on behalf of 256mbit capacity, 51 for 512mbit capacity.
6th, 7 digits-the number of data line pins, 08 for 8-bit data, 16 for 16-bit data, 32 for 32-bit data, 64 for 64-bit data.
11th Place--wired "-".
14th, 15 bits-the rate of the chip, such as 60 for 6ns;70 for 7ns;7b 7.5ns (cl=3), 7c for 7.5ns (cl=2) 80 for 8ns;10 10ns (66MHz).
