Description
NT128S64VH4A0GM is a 144-pin Synchronous DRAM Small Outline Dual In-line Memory Module (SO DIMM) that is organized as a 16Mx64
high-speed memory array. The SO DIMM uses four 16Mx16 SDRAMs in 400mil TSOP II packages and achieves high-speed data transfer rates
of up to 133 MHz by employing a prefetch / pipeline hybrid architecture that supports the JEDEC 1N rule while allowing very low burst power.
All control, address, and data input/output circuits are synchronized with the positive edge of the externally supplied clock inputs. All inputs are
sampled at the positive edge of the externally supplied clock (CK0). Internal operating modes are defined by combinations of the
RAS , CAS , WE , S0 , DQMB, and CKE0 signals. A command decoder initiates the necessary timings for each operation. A 15 bit
address bus accepts address information in a row/column multiplexing arrangement.
Prior to any access operation, the CAS latency, burst type, burst length, and burst operation type must be programmed into the SO DIMM by
address inputs A0-A9 during the mode register set cycle. The SO DIMM uses serial presence detects implemented via a serial EEPROM using
the two pin IIC protocol. The first 128 bytes of serial PD data are used by the DIMM manufacturer. The last 128 bytes are available to the
customer.
All Nanya 144-pin SO DIMMs provide a high performance, flexible 8-byte interface in a 2.66" long space-saving footprint.
