Camas, Wash.--Jan. 22, 1998--Sharp Electronics Corp. announcedthe availability of an 8-Mbit flash memory device that uses boot-blockarchitecture and eliminates the need for EEPROMs to allow for smaller,thinner, and lighter mobile devices.
The LH28F800BG contains both a large block of standard memory (32-K words x 15 blocks) and a smaller block of erasable memory (4-K words x 8 blocks) that can store small quantities of data.
Existing cellular phones use flash memory with uniform block sizes to store their enormous communications control programs and use EEPROMs to store and erase data in single-byte units for telephone number lists and owner ID numbers.
The new 8-Mbit device is ideal for use in cellular phones, PDAs, and set-top boxes because its small size blocks allow data to be stored and erased in smaller units. It reduces the number of required chips and contributes to development and manufacture of lighter weight, thinner profile, and more compact products.
The LH28F800BG (8-Mbit) device operates at a low voltage of 2.7-V read/write/erase and at a high speed up to 120 ns at 2.7 V. The 48-pin TSOP and 48-pin chip size packages (CSPs) are compatible with Sharp's existing line of flash products and are also Intel compatible.
