its also called content addressable memory .Content-addressable memory (CAM) is a special type of computer memory used in certain very high speed searching applications. It is also known as associative memory, associative storage, or associative array
Usually high speed SRAM with CAM (content addressable memory) line address tags.
Content Addressable File Store was created in 1982.
Some companies that make content addressable storage include SAN Direct and Lizard Tech. Another company that makes content addressable storage is Caringo.

a byte is abasic storage unit in memory. when application program instructions and data are transferd to memory from storage devices. byte addressable memory refers to memory address that is accessed one byte (8 bits) at a time as opposed to 2 byte(16 bits), 4 byte(32 bits) or 8 byte(64 bits) addressable memory.
Cache memory is composed of 2 types of memory:RAM (Random Access Memory) this is used to store the data copied from main RAM as a series of Cache LinesCAM (Content Addressable Memory) this is used to store the main RAM address for each Cache Line, so the data in Cache Memory can be found and associated with main RAM. The CAM also typically contains special flags (e.g. the "dirty" bit - indicating that the Cache Line has been modified and will have to be written back to main RAM).Cache memory also contains controller logic to coordinate the necessary actions.The first computer built to have what we now call Cache memory was the IBM Stretch 7030 introduced in 1961. However IBM at the time called this feature "Virtual memory". (Confusing isn't it?)

64 GB of RAM.
There is no such thing as 14-bit byte addressable memory. There IS, however, 16-bit byte addressable memory, which I hope is what you meant. In that case, you simply divide 16 by 4 to get 16/4 = 4 nibbles. If you did in fact mean 14-bit address, then it would be 14/4 = 3.5 nibbles
The bit addressable memory in 8051 is compose from 210 bits: - bit address space: 20H - 2FH bytes RAM = 00H - 7FH bits address; - SFR registers; The following addresses are NOT bit addressable, only 1-byte addressable: - 32 bytes RAM from 00H to 1FH (R0 - R7 registers in all four banks); - 80 bytes RAM general user from 30H to 7FH.
Depending on the architecture of the computer one addressable memory location might be called a word, a character, a parcel, a decimal digit, a byte, etc.
