Main MemoryMain memory is located in a dedicated unit called "Core Unit". Modern memory chips occupy little space but further expansion is expected (such as building ROM based on diodes-matrixes, support for Virtual Memory etc.) hence the extra space needed.
Memory is wired in 16-bits words (as opposite of 8-bits bytes). This means that a given address allways referres to a memory location which is 16-bits wide. A number of instructions have been provided for manipulating bytes within words but that is only once the content has been read into a CPU register.
At present, the 64 Kwords addressable space is "real", that is no support for Virtual Memory yet exists.
