Mobile LPSDR devices are quad-bank DRAM that operate at 1.8V and include a synchro-
nous interface. All signals are registered on the positive edge of the clock signal, CLK.
Read and write accesses to the device are burst oriented; accesses start at a selected
location and continue for a programmed number of locations in a programmed se-
quence. Accesses begin with the registration of an ACTIVE command, followed by a
READ or WRITE command. The address bits registered coincident with the ACTIVE com-
mand are used to select the bank and row to be accessed (BA0 and BA1 select the bank).
The address bits registered coincident with the READ or WRITE command are used to
select the starting column location for the burst access.
The device provides for programmable READ or WRITE burst lengths. An auto pre-
charge function may be enabled to provide a self-timed row precharge that is initiated
at the end of the burst sequence.
The device uses an internal pipelined architecture that enables changing the column
address on every clock cycle to achieve high-speed, fully random access. Precharging
one bank while accessing one of the other three banks will hide the precharge cycles.
The device is designed to operate in 1.8V memory systems. An auto refresh mode is pro-
vided, along with power-saving, power-down, and deep power-down modes. All inputs
and outputs are LVTTL-compatible.
The device offers substantial advances in DRAM operating performance, including the
ability to synchronously burst data at a high data rate with automatic column-address
generation, the ability to interleave between internal banks in order to hide precharge
time, and the capability to randomly change column addresses on each clock cycle dur-
ing a burst access.
