GENERAL DESCRIPTION
The M12L64322A is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 524,288 words by 32 bits.
Synchronous design allows precise cycle control wi0th the use of system clock I/O transactions are possible on every clock cycle.
Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a
variety of high bandwidth, high performance memory system applications.

INPUT FUNCTION
Active on the positive going edge to sample all inputs
Disables or enables device operation by masking or enabling all
inputs except CLK , CKE and DQM0-3.
Masks system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior new command.
Disable input buffers for power down in standby.
Row / column address are multiplexed on the same pins.
Row address : RA0~RA10, column address : CA0~CA7
Selects bank to be activated during row address latch time.
Selects bank for read / write during column address latch time.
Latches row addresses on the positive going edge of the CLK with
RAS low.
Enables row access & precharge.
Latches column address on the positive going edge of the CLK with
CAS low.
Enables column access.
Enables write operation and row precharge.
Latches data in starting from CAS , WE active.
