description  
The TMS664xx4 series are 67108864-bit synchronous dynamic random-access memory (SDRAM) devices  
which are organized as follow:  
Four banks of 1 048 576 words with 16 bits per word  
Four banks of 2097152 words with 8 bits per word  
Four banks of 4194304 words with 4 bits per word  
All inputs and outputs of the TMS664xx4 series are compatible with the LVTTL interface.  
The SDRAM employs state-of-the-art technology for high-performance, reliability, and low power. All inputs and  
outputs are synchronized with the CLK input to simplify system design and to enhance use with high-speed  
microprocessors and caches.  
The TMS664xx4 SDRAM is available in a 400-mil, 54-pin surface-mount thin small-outline package (TSOP)  
(DGE suffix).  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.  
Products conform to specifications per the terms of Texas Instruments  
standard warranty. Production processing does not necessarily include  
testing of all parameters.
