The 256Mb Mobile DDR SDRAM is a high-speed CMOS, dynamic random-access mem-
ory containing 268,435,456 bits. It is internally configured as a quad-bank DRAM. Each
of the x16’s 67,108,864-bit banks is organized as 8192 rows by 512 columns by 16 bits.
Each of the x32’s 67,108,864-bit banks is organized as 4096 rows by 512 columns by 32
bits. In the reduced page-size (LG) option, each of the x32’s 67,108,864-bit banks are
organized as 8192 rows by 256 columns by 32 bits.
Note:
1. Throughout this 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. Addi-
tionally, the x16 is divided into 2 bytes: the lower byte and the upper byte. For the lower
byte (DQ[7:0]), DM refers to LDM and DQS refers to LDQS. For the upper byte
(DQ[15:8]), DM refers to UDM and DQS refers to UDQS. The x32 is divided into 4 bytes.
For DQ[7:0], DM refers to DM0 and DQS refers to DQS0. For DQ[15:8], DM refers to
DM1 and DQS refers to DQS1. For DQ[23:16], DM refers to DM2 and DQS refers to
DQS2. For DQ[31:24], DM refers to DM3 and DQS refers to DQS3.
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.
