WHAT is a bit?
a bit is a simple value of 1 or 0
8-bit memory is just a memory that can store 8 bits

hehe as you saw above, a bit is just a 1 or a 0
so that type of memory can store from
0000 0000 to
1111 1111
1111 1111 is
1×2^0 + 1×2^1 + 1×2^2 ….
1 + 2 + 4 …. 255
the highest no in an 8 bit memory is 255 and that makes 256 values including 0
of course that’s not much
but having memory organised in more bits like 32 or 64 provides you with much more values
