The 128Mb Mobile LPSDR is a high-speed CMOS, dynamic random access memory con-
taining 134,217,728 bits. It is internally configured as a quad-bank DRAM with a synchro-
nous interface (all signals are registered on the positive edge of the clock signal, CLK).
Each of the x16’s 33,554,432-bit banks is organized as 4096 rows by 512 columns by 16
bits. Each of the x32’s 33,554,432-bit banks is organized as 4096 rows by 256 columns by
32 bits.
Mobile LPSDR devices offer substantial advances in DRAM operating performance, in-
cluding the ability to synchronously burst data at a high data rate with automatic column-
address generation, the ability to interleave between internal banks to hide precharge
time, and the capability to randomly change column addresses on each clock cycle dur-
ing a burst access.
Note:
1. Throughout the data sheet, various figures and text refer to DQs as DQ. DQ should be
interpreted as any and all DQ collectively, unless specifically stated otherwise. Addition-
ally, the x16 is divided into two bytes: the lower byte and the upper byte. For the lower
byte (DQ[7:0]), DQM refers to LDQM. For the upper byte (DQ[15:8]), DQM refers to
UDQM. The x32 is divided into four bytes. For DQ[7:0], DQM refers to DQM0. For
DQ[15:8], DQM refers to DQM1. For DQ[23:16], DQM refers to DQM2, and for
DQ[31:24], DQM refers to DQM3.
2. Complete functionality is described throughout the document; any page or diagram
may have been simplified to convey a topic and may not be inclusive of all requirements.
3. Any specific requirement takes precedence over a general statement.
